Types of Tankless Water Heaters
There are 2 choices you must make when you select a tankless water heater. First, choose between the following:
-Non-Condensing Tankless Water Heater. These units are more affordable, however they are less efficient and can cost more to run.
-Condensing Tankless Water Heater. These units are more efficient and effective, however they are usually more expensive.
Next, choose where in your home the heater will be installed:
-Internal heaters are inside the home and usually reside in basements and closets. Internal heaters require venting pipes and are usually routed through a vent in the side of the home.
-External heaters are hung outside the home, eliminating the need for venting pipes. External heaters are very popular, but they are not recommended for parts of the country with very cold temperatures and many freezing nights.
There are several advantages to installing a tankless water heater, including the aforementioned endless supply of hot water. Tankless water heaters last an average of 20-25 years, twice as long as tanked water heaters. Tankless heaters are also smaller and use less space than a tanked heater, resulting in a lower gas bill. The average energy cost to run a tankless water heater each year is $225, an $82 savings to a tanked heater’s $307 per year cost. Finally, tankless water heaters add increase the re-sale value of a home.
Buying a tankless water heater involves higher purchase and instillation prices compared to tanked water heaters. (County and municipality tax breaks can sometimes counterbalance these costs, check here to see if you are eligible for any rebates.) Tankless water heaters must be vented, meaning they need venting pipes, a vent added to the home, and possibly an new gas line added, all of which costs money. Exterior tankless heaters cut the cost of venting pipes and a vent. We suggest installing a water heater as close to the home’s gas meter as possible.
Tankless heaters must be serviced annually, to a cost of $79-$100 per year. Homeowners are able to service the heaters themselves, which usually takes around 4 hours once per year. Additionally, tankless water heaters take more time to send more hot water to your faucet than tanked heaters. Tankless heaters also do not run out of hot water, allowing for longer showers and more water consumption. The key to combating this is to time your showers and be conscience of your water usage.
