If you are building a new home in South Western Ontario or need to replace your old water heater, you may be wondering if you should choose a tankless water heater. This type of water heater is known to be efficient and many have chosen it for their new homes. On the other hand, they may not be economical.
You more than likely have heard from manufacturers that this type of water heater will cut your energy bill in half, which would be great since heating water is around 30% of the energy budget of the average household in Ontario. But, does a tankless water heater really give you these great savings?
Well, in order to answer that question, you must look at the water heater. This type of heater uses high powered burners that will heat water fast while it goes through a heat exchanger. This actually saved around 22% more energy than water heaters that used a gas fired storage tank. The main problem is that you may save money in this area, but you also have to consider that a tankless water heater is much more expensive and in all reality will take around 22 years for you to make back your investment.
Another thing to consider is that many homeowners that decided to go with a tankless water heater had to upgrade their electrical service in order to provide enough power for the entire home to use this type of heater.
Recent studies using tankless water heaters and gas storage tank water heaters revealed that for an average family using 45,000 gallons of water over an 11 year period showed that tankless heaters still ran hot and cold instead of the boasts by manufacturers stating endless hot water. Another problem that was if you only wanted a small amount of hot water to come from the faucet, the burner might not ignite so you would only achieve cold water. There is not instant hot water with a tankless heater as the water must heat up so just like heaters with tanks, you will always have cold water first as it will be pushed from the pipes until the hot water warms up and heads to the faucet. If you lose electricity for any reason, your tankless heater will not provide any hot water as it relies on electricity to warm the water.
Another high cost of the tankless heaters is that they will need serviced at least once per year by a professional. These models seem to have scale buildup that must be flushed from the heater as the deposits will reduce the flow of water and damage the unit.
