Size really does matter

As Adelaide’s largest supplier and installer of hot water services in South Australia we get asked a lot of questions about making the right choice of water heater.
Probably the most common question asked is “how much will it cost to install the biggest instant hot water service
they make?”

That answer is straight forward as we have rates for standard change overs and upgrades, BUT what people are not accurately educated on are a few important
factors.

• Do you have a large enough gas pipe at the location of the new hot water service?  The larger the unit the thirstier it will be for gas and in the colder months of the year is when the demand will be the highest, so although it may seem to cope during summer when winter comes you will see the performance drop off significantly.  Your warranty will not cover faults relating to inadequate gas supply and these issues can be very expensive and not to mention dangerous.
• Are the incoming and outgoing water pipes large enough to firstly supply the new hot water service say 27 litres per minute of
  cold water and then are the pipes inside of the home large enough to disperse 27 litres per minute of hot water once produced?  In many cases this answer is no when upgrading on an existing home.

With these two vital points in mind you could be paying for a system that will never really work to its full capacity.  Many plumbing companies will sell you the largest Bosch, Rheem or Rinnai continuous flow hot water service you can buy, but there are very few who will take the time to educate the customer on the correct unit for your home or business.  Don’t waste money on a big water heater for your home that you’re never going to see the real benefits of, speak with a hydraulic consultant today.
