Commonly installed in offices, commercial kitchens and function facilities the Rheem Lazer boiling water units supply boiling hot water on demand for tasks such as making coffee, tea, soup, cooking and cleaning of work areas.  The convenience of having water suitable for making instant soup or ready to clean dirty floors is something many people enjoy day to day throughout multiple locations across the state of South Australia.

Rheem Lazer Review

The flexibility of having these boiling water systems available various sizes allows you to get a system which will cater to the demands of every situation.  There are 3 different models on offer and they are as follows:

Lazer Eco

At the entry level of the range from Rheem offer boiling water through there Eco range.  As the name suggests it is the more basic of the 3 systems on offer.  This unit comes in 3 litre, 5 litre and 7 litre options.  It has a simple one button control and is finished off in a sleek powder coated white cover.

Lazer Office

Fully programmable the Office range offers unique features allowing for the system to be automatically turned on during periods of high demand and off again during periods when not in use ie: weekends for office buildings.  With a choice of either stainless steel or powder coated white the Office range has been awarded an International award for design.  Available in both 3 litre and 5 litre models the Office range makes a fantastic addition to any work place.

Lazer Commercial

Once again as per the Office range the Commercial is fully programmable and available in both stainless steel and powder coated white.  The big advantage of the commercial range is its ability to deliver up to 247 cups initially from the massive 40 litre model.  Ideally suited to establishments such as fast food outlets and restaurants where a large amount of boiling water is needed for tasks such as washing down floors and sanitisation of food preparation areas.

When we look at the maintenance required on these systems throughout their life span there a few common tasks which we deal with:

• Faulty cold-water inlet solenoid: This solenoid controls the delivery of cold water into the hot water tank.  During the life of the system this valve can wear out and needs replacing with a new solenoid valve.
• Calcified outlet tap: Adelaide is known for having hard water and it in turn shortens the life of many plumbing valves and fittings.  The boiling water systems dispenser is no stranger to this problem and during the unit’s life will most likely need replacing due to no delivery of hot water.
• Failed element: When a client notices that the unit is no longer delivering boiling water or only warm water it is a sign that the element is deteriorating and should be upgraded.
• Broken temperature sensor probe: If a boiling water unit is continually discharging water at a quick rate through the vent pipe it can indicate that the temperature sensor probe is not communicating properly and not providing the CPU with the correct temperatures.
• Malfunctioning CPU: In some cases where all the above noted issues are working ok and there is still a problem with the unit not operating to the manufacturers specifications then it will most likely be a faulty CPU or control board

The Rheem Lazer boiling water units today have a good share of the hot water plumbing market and keep our technicians busy with general servicing and replacements as nothing lasts forever anymore.  Through continually working with these systems we have become familiar with how these units operate and what parts are needed to be carried in the service vehicles to enable immediate repairs as no one likes going without there morning coffee.  If your experiencing difficulties with your boiling water unit let us assist you, we cover all locations across Adelaide and in most cases,  we will be out to you in the same day.

The South Australian Government has various options in the form a money back rebates for customers replacing their water heater or putting in a completely new style of heater in.  Depending on your situation the variables are all different and we will go through them in this post.

What do I need to do to qualify?

It’s a question we get asked a lot will I qualify for the cash rebate when I get a new hot water service?  There a few items you need to tick on the list first:

1. If you are replacing an existing heat pump such as Quantum or Chromagen it must be a minimum of 6 years of age, so in short if your heat pump has lasted past its cylinder warranty which is typically between 5 and 10 years (every manufacturer is different) then you will be entitled for the rebate providing the work is performed by licensed trades people. The model and brand which you choose will affect the rebate.  For example, a Stiebel Eltron 302L with smart element currently has a $1,080 plus gst rebate on it, it’s a great saving.
2. The same rebate would apply if you were to remove an existing electric storage water heater such as a Rheem Optima 250L or DUX 250L and replace it with the Stiebel Eltron 302L smart element water heater.
3. Natural gas has a few different options to be eligible for government rebates which apply to this fuel type. If you currently have natural gas connected but are using electricity for heating of the water and you decide to swap over to natural gas hot water system such as a Rinnai Infinity 26, Rheem Metro or Vulcan, there is currently $500 in rebates available.  If you do not have any gas connected to the property and opt to have it installed, you will firstly get the $500 as mentioned above when connecting a gas water heater and am additional $1,000 for connecting a gas meter to property.
4. Solar hot water will also entitle you to a government rebate. As mentioned early in the article like heat pumps if you replace an existing solar hot water service with a newer system providing it has served the life of its warranty (as a guide) you will be entitled to fill out the correct form and apply for your rebate.
5. As with the situation of a new heat pump installation if you decide to upgrade from a dedicated electric storage water heater such as a Thermann or Ever Hot to a solar heated water service such as a Solar Hart, Edwards, Apricus or Rheem Lo-Line then you will also be eligible for government rebates. These all vary due to the many different models available to customers in Adelaide.

Lower utility bills and money in the bank

It is a situation where you can’t lose, not only do you get to claim up wards from $1,000 on rebates but the technology which you have selected will be using far less energy leading to on going running costs on a business or households to be lower.  It’s a bonus the utility bills are going to be lower and your impact to the environment will be decreased.

*please note the information in this article was current at the time of publishing.

Quite often the question is asked, “how can I get hot water to a kitchenette or a hand basin without having to install a huge storage cylinder?”

Many years ago, there was no option but to consume the entire cupboard below the sink with a mains pressure electric storage hot water
cylinder either 25 litres or 50 litres in delivery capacity. You will still see a lot of these systems in operation especially in the older office buildings throughout Adelaide’s CBD. Today there is another option with major benefits:

• Does not store water
• Only takes up a small space in the cupboard
• No need for drainage pipes
• Heats water only as required (instant)
• Permissible operation pressure of 1000kpa
• Three adjustable temperature settings
• No ongoing regular maintenance
• Whisper quiet operation
• Easy installation
• Sleek looking design
• Suited to areas with low water flow rates
• 5-year warranty on domestic installations
• Can be partnered to multiple draw off points
• No risk of flooding from a burst storage cylinder (suited to multi storey office blocks)

Introducing Stiebel Eltron

Stiebel Eltron have been in the water heating market now for nearly 100 years when back in 1924 Dr. Theodore Stiebel founded the company in Berlin. Today the company is better known for its green energy low carbon systems through the delivery of heated water via heat pump technology. Stiebel Eltron also offer compact tankless instant electric water heaters for end users where their demand is low i.e. kitchenettes, laundry sinks, doctors rooms and hand basins.

The compact single phase instant electric water heaters come in four different models:

• DHCE 6/50
• DHCE 8/50
• DHCE 8/60
• DHC 4

These models can be installed below bench or directly above the sink depending on its desired use. They come in a sleek modern looking outer case, quiet dispenser, easily operated and guaranteed reliability under a 5-year manufacturer’s warranty (domestic applications only).

Case Study

Today many new homes are being built with multiple bathrooms that are typically positioned close to each other allowing for one large continuous flow gas water heater to supply hot water to these various outlets such as baths, bidets, showers and basins. What is neglected unfortunately is the kitchen sink, but there is a solution.

Delivery of water from a hot water service to the kitchen sink has a terrible reputation for taking a long time and by the time it arrives the person is likely to have finished using the tap. But with the installation of a Stiebel Eltron under bench unit which is plumbed up directly to the hot feed instead of the cold any water that leaves the properties hot water service for delivery to the kitchen sink is immediately used as intended “hot”.

Because the under-bench unit is connected to the hot supply pipe it utilises any of the water being fed to it from the properties water heater. Initially the under-bench unit will consume a little bit more electricity as it heats to cooler water in the hot pipe, but as the water temperature increases as it makes its way over across to the kitchen the Stiebel Eltron system starts to use less energy.

What does this mean? It means no longer are property owners waiting for hot water to finally arrive at the tap wasting countless litres of water (on average 1.5 litres of water is wasted every time the tap is turned on, that’s 5,475 litres of water per year, working on the average house hold turning on the hot tap at the kitchen 10 times per day). Instantly upon turning on a hot tap there will be water at the selected temperature.

How can it be achieved?

It doesn’t matter whether you have an existing property, building a new property or renovating these types of water heaters can be adapted to suit your demands. There is always going to be water plumbed up to a kitchen and it doesn’t have to be hot water these systems are designed to take cold or hot water feed pipes. The electrical supply cables to one of these systems is single phase (which is what every property who has electricity is connected to) and must be on a dedicated circuit which once again is a very simple process to have performed.

If you are considering your options for hot water to an office kitchenette or a commercial fit out contact us today and let us further discuss the options to suit your requirements. You will be amazed just how efficient these systems are and just how little space they require to be installed.

When was the last time you heard someone say something was free, its pretty rare! But when we start to discuss hot water there is an option that gives you the ability to take advantage of free energy to create hot water for nearly 8 months of the year (depending on your geographical location and aspect of the house).

Solar that’s right using the energy from the sun today allows businesses and homes to create electricity for either credits into the grid or use around the home, but another option is using solar panels which have water pumped through them.

By using solar water panels mounted to a roof either directly or via a pitched frame it typically willsoalr energy from the sun its FREE allow a domestic water to affectively operate during summer (and those other months where we get hot weather) without any further contribution via another energy source such as gas or electricity.

Another bonus for businesses and large-scale set ups such as apartments, hotels and aged care facilities is that the solar energy will contribute significantly to pre-heating. Due to the large-scale volume of water properties such as these commercial and industrial properties consume its unrealistic to think the solar water heating will provide 100% of the buildings requirements but it certainly allows for a good portion of pre-heating meaning that natural gas or propane (in most cases) only will be then used to heat warm water which keeps gas consumption down and hence lowers the utilities bills.

Like most things today nothing last forever and infrastructure such as these also need maintaining during their life. The average expected life span of solar water panels is between 15 to 20 years (depending on manufacturer and environmental conditions). During this period, you can expect to have repairs performed on items such as the hot and cold-water pressure relief valves, seals which join the panels together, cleaning of the panels to ensure they are performing at their optimal efficiency and anti-frost valves replaced in frost prone areas of the Adelaide Hills such as Stirling, Crafers, Aldgate, Bridgewater and Hahndorf to list a few of the more common locations of South Australia.

One important aspect to remember about solar panels is successfully gaining and maintaining access to work on these or even replace when the time comes. When we look at commercial and industrial properties majority of the time there are tie down points for our workers to harness themselves onto and ladders installed via roof access hatches to safely get onto and off the work place where the panels are installed. In domestic set-ups it can be little more challenging, so we need to attend the site with a E.W.P. (elevated working platforms) or have a scaffold erected. Working safely at heights is never a short cut worth taking as everyone deserves to go home from work each day
without injury.

If you don’t currently have solar water heating panels installed at your business or home let us help you with technical solutions based upon your requirements. On larger projects we have had up to 20 panels banked/manifolded together for pre-heating purposes and on smaller scale domestic homes we have had just one panel installed. Each case is different and that’s where our experience will be to your benefit, let’s work together on decreasing your energy bills.

It’s here the all new Rinnai range of gas water heaters (see image).  The overall look is very similar just a minor change in colour, but there are some cool new features which when you look a little closer have really put Rinnai in front of the hot water game.

New Technology In Hot Water Systems

So, what’s new:

• One the big bonuses for us plumbers is that the newer systems are lighter so the installation process for us is easier, especially in those situations where the unit may need to be installed in a particularly awkward location.
• You will now see there is a small black sensor which hangs out the bottom right hand side of the unit.  This now enables the system to more accurately adjust to its surrounding environment according to the outside temperatures it is working in.  Through detecting the external condition’s the system will calculate how much energy is required to most efficiently heat the water.
• All three systems 16 litre, 20 litres and 26 litre all now provide a 6-star energy rating where as some of the competitors on the market today still only produce a 5-star
• 10-year warranty on the copper heat exchanger inside the unit.
• Compatibility with two fuel types being either natural gas or propane offering people both in metro Adelaide and the Adelaide Hills the ability to have access to this new form of technology.
• The optional addition of up to 4 temperature control pads.  With the addition of temperature control pads the energy consumption from the hot water service itself can be controlled by only selecting the required temperature of hot water delivered through the faucets in property allowing for the unit’s energy consumption to be decreased.
• The gas test point has been made slightly longer and ever so slightly thinner allowing for much easier connection of the digital gas manometer upon completion during the commissioning stages.

New Rinnai Water Heaters

Since the introduction of these new improved Rinnai water heaters we have had the privilege of installing many of these units across Adelaide and received positive feedback from all our clients.  If you are looking at upgrading to the new Rinnai range of water heaters speak with us today and we can help you select the right fit for your demand.

 

 

 

Probably one of the more common questions we get asked, how can I stop my hot water service
from leaking?

Type Of Water Heater

The first thing we ask our customer is what type of water heater do you own? Is it a storage tank or a small box which hangs on the wall? The likelihood of being able to fix a continuous flow hot water (small box on the wall) are greater then that of a storage tank.

Regardless there is typically always a shut off valve which will temporarily stop the flow of water until a service technician can attend.

If a customer reports that a storage style water heater is leaking it is usually an older model potentially 10 plus years old and the cylinder has most likely developed corrosion internally and now started to leak.

Don’t Let The Problem Get Worse

Sometimes these leaks start off as a very minor issue and can escalate over time. Unfortunately for this type of problem there is no fix and the storage tank will need to be replaced. If how ever the tank or heat exchanger itself is not leaking there could well be an associated part
which is leaking. Items such as high temperature and cold-water relief valves can fail during the life of a hot water service and start to leak.

These are quite easy to fix and are not going to cost you a second mortgage.

stocked with all the common parts to help you get your problem back under control. We also carry

It was approximately 8 years ago that the government introduced incentives to have a Heat Pump hot water service installed to homes and businesses.  It is now that majority of these systems are coming out of there warranty periods and the tanks are starting burst open.  This is leaving the home owners and business owners in a position where they now need to consider their options for another 8 years, replace with another heat pump or swap back to dedicated electric water heaters on J tariff.

Heat Pumps

Well in most cases the choice is very clear, revert to the electric storage water heaters and ensure they are wired up on off peak electrical.  The reason for this is that the heat pump water systems are extremely expensive to purchase without the huge government rebates any more.  Unfortunately, many customers didn’t have a good experience with the overall heat pump operations, many complaining about excessive noise and un reliable refrigeration components located either on top or at the front bottom.

What is the advantage to changing back to a conventional 250L electric hot water service?  The tanks now come with an optional 10-year warranty, you only need a licensed plumber to service these during the heaters life (not a refrigeration mechanic and plumber), they are silent in operation and can be installed in discrete locations with zero ventilation such as laundry cabinets and under kitchen benches (sizes may vary).

Manufacturers

The range of manufacturers who produce these systems for the Adelaide Plumbing market is also far wider than previously experienced.  Manufacturers such as Aqua MAX, Rinnai, Rheem, Vulcan, DUX Stiebel Eltron and Thermann all provide systems in various sizes with options on warranty periods, the choices are set up to suit most budgets.

Probably the biggest bonus of all is that we carry these in stock at our warehouse giving you the ability to get a same day change over performed of your water heater across Adelaide.  Ask about our options to pay for your hot water system on your credit card today!

A hot water service which is not working correctly can contribute significantly to any home or businesses energy bills.  It doesn’t matter what source of energy is being used whether it be electricity, gas or solar (sun) via panels on a roof.  If components have not been installed correctly or over time have started to fail then the system itself can start to operate inadequately and could be using huge amounts of energy leading to very nasty surprises when your next Origin or AGL retailers bill arrives in post.

For example, we recently attended a client’s home in Adelaide where they were questioning their excessive electricity bills.  They are living in a 2 bedroom and 1 bathroom home in the heart of the city off Hutt Street.  The hot water service being approximately 7 years of age and was a 125 litre DUX model.  The latest electricity bill was $612 for the quarter just gone.  The customer lives at the home by herself and is very mindful of electricity usage as the costs of energy consumption keep sky rocketing in South Australia.  As you will see in the image on this page that the electrical components and the thermostat all appear to be in bad condition.  When we performed some test on these parts with a multi meter it showed that the thermostat itself was not turning off, so the water heater was constantly heating 24/7.  By doing this it had put excessive strain on the wiring also which could have resulted in other potential problems such as an electrical fire one day.

To have this problem rectified we firstly replaced the wiring from the switch board to the water heater.  This hot water service is controlled via 20-amp circuit breaker dedicated to feeding the power to the this DUX unit only.  We then changed over the Robert Shaw thermostat and checked that it was turning on and off (brand new).  Because this water heater is only 125 litres it is not on J tariff electricity (off peak) it runs off M tariff (peak electricity) so we were able to leave the hot water service under load ensuring the customer will continue to get hot water.

If you suspect that your gas or electricity bills are too high it is important to have it checked out by a hot water specialist today before winter hits and your boiler starts to come under extreme pressures due to the changes in temperature.
