Most energy efficient tankless water heaters
Ranging in size from 20 to 80 gallons or larger and fueled by electricity, natural gas, propane, or oil, storage water heaters work by heating water in an insulated tank. Demand water heaters should be sized according to the required gpm flow rate and temperature rise during the winter required for your largest expected hot water fixture usually a shower. Any form of hydronic space heating — hydronic baseboards, radiators, or radiant heat — can be provided by boiler systems. A much better approach is to do some research now. Read more.

Another approach, introduced in the U. As such, if you live in a colder climate, you need a larger model with a higher flow rate to produce the same amount of hot water a smaller one can in a temperate climate.
In very tight houses, drawing combustion air from the house and passively venting flue gases up the chimney can sometimes result in lower air pressure inside the house see Building Envelope.
Additionally, the report noted that tankless gas models had higher installation costs, thanks to the need for electrical outlets, upgraded gas pipes and a new ventilation system.
