I actually went to a Rinnai condensing boiler class. I would have to see what type of options there are for domestic hot water.

In my limited experience with tankless heaters I have seen them to be very expensive. We're talking thousands of $$$ installed compared to $750 for a tank water heater installed. The cost gets very large if you go up to a 90% efficiency. You start getting into different venting requirements with those.

The tankless is good if you use alot of hot water for instance a large family or a commercial application.

The rinnai condensing boilers are very high maintenance also. Unless you are using a lot of hot water and/or have some money to spend, I would recommend a standard tank water heater. There are also high recovery tank water heaters that are better on the pocket book when compared to the tankless.

I could shop around for some tankless options and see just how much they cost.
