water heater and boiler in one unit or use a tankless water heater as a boiler

i am trying to find a boiler/water heater that will do 2 thing in one unit
where boiler water does not mix with domestic hot water

i know baxi luna has that but feed back was not that great

and one more thing

would it damage a tankless water heater if i use it as a boiler ( pipes and radiators are black iron)
i know how to hook it up i just thought that it might be a cheaper option

I am not a proponent of that but check with the local codes. Many areas require an "H" stamp when used for heating.

The following are combi boiler or combi heaters depending on which approvals they have, all with separated hydronic/DHW circuits:

1. Crown/Burnham MWC116E(L/N)T
2. BaxiHT 330 Combi
3. Embassy Ambassador Onex
4. Quietside QVM9-150W1-NG
5. Trinity Ti200c
6. Triangle Tube Excellence
And soon I hear the Navien CH

Quite a few of those have ASME, CSA and other approvals.

I agree with not using a tankless as a main boiler, it just wont last, as a secondary perhaps such as a auxillary boiler for a finished basement in a house that has forced air might be a good use for it.

I think a cheaper option would to use a solar hot water heater. They are cheap and easy to set up and work brilliantly with a tankless hot water heater too.

Got to wonder about a web site that says "hot water heater" instead of "water heater". If the water is hot no need to heat it. Note you make the same mistake and it is your first post. Could this be spam? Stick around if your not a spammer but till we know you careful with the links.
