How exactly does a tank-less hot river radiator work? ...
Answers: There are a series of heaters that only come on when 'hot water' is call for. some people refer to tank-less marine heaters as 'on demand' but that can be a little misleading. When hot river is called for the existing river in the pipes will be pushed out by the 'hot water' resulting within some not so hot water for a few second.
The advantage is that beside a standard water stove you are keeping water hot 24/7 at a cost for gas or electirc. With the current tankless you only use your gas/electric when indispensable resulting in a nice funds.
Other factors to consider are the number of individuals in your house, number of hip bath rooms, dishwasher, sinks etc. the tankless neeeds to be sized properly and most important--vented exactly as manufacturer states.
The initial cost can be 2-3 times as dignified as a standard water oven but in the long run you will liberate.
