Tankless Water Heaters

We're considering Tankless Water Heaters now that we've got several years on our traditional tank storage water heater. The model we had was efficient for it's time, but the improvements in technology over the past ten years allows us to look at new technology.

We spend more to heat water than we do to air condition, so we stand to save a good bit of money with a more efficient system. Tankless systems only heat water when it is needed, so no energy is wasted keeping the water warm when it isn't being used.

In researching this, I came across three different sources of information:

  1. Advertising from Manufacturers (Rinnai has an informative site).
  2. More neutral information on the web such as Wikipedia.
  3. Personal friends with experience (such as the friend who built this house).


What I found interesting is because of the limited amount of time available to heat the water, you need more energy at the time the water is being used. This means installing a tankless water heater may require larger gas main and venting.

Will keep you posted as our search continues. We've got a few retailers and contractors we'll be talking to about our needs.
