how about wall hung boilers that include domestic water heating

Jimbo_3

I have some cast iron radiators so I've decided to use a primary secondary piping layout. The boiler is quite small and hangs on the wall. It should provide domestic hot water too. If for some reason it cannot provide enough hot water during the winter, as city water temperature drops. Are there any temp tanks available today that can be used to increase operating efficiency, or should I just get more creative and use a small hot water tank as a holding tank?

What kind of wall hung boiler

are you considering? I am familiar with a wall hung boiler that has a built in heat exchager and its design determines how much water, and at what temperature, is available. A stand alone storage tank is always able to produce more DHW volume for an initial drawdown than the wallhung with HX can. If you select priority heating for the DHW you will most likely not run out of DHW regardless of outdoor temperature.
