all that has been said so far..what is the heat loss? You will need a lot of baseboard to put out much heat at a temp lower than 160F...and you can't run a water heater that high w/o scalding protection....kpc

    Baseboard heat install

    Has any one or is it even possible to grab a wet loop off a gas fired hot water heater directly without a seperate heat exchanger?

    You could...

    but if its being used as a DHW heater also, you'll expose the end users to the possibility of contracting Legionaires disease. If that doens't bother you, then I guess you could...

    It can be done

    We did the exact same thing in my old bosses parents home , on an oil fired heater . We used a bronze circ and connected it directly to the heater . That was 15 years ago , before I became educated about Legionella by the pros here .

    There is a chance of contaminating the domestic water side of the home . Some forms of bacteria can thrive in a baseboard loop connected to a water heater used for hot water . A few experts that post here regularly can give you more info on this subject . Might take some time , I think they're all at Wetstock .

    Seems like cheap insurance to add a heat exchanger to the heater to keep the baseboard water separate .

    Still probably not the greatesst idea to do heat open-loop but when I did one many years ago. I added a couple of valves so the cold water went into the supply side of the water coil in the air handler in the non heating season or into the cold inlet of the tank in the winter. They had to be manually switched but it allowed to continiously flush the heating loop. There was a condensate pan under the coil just like an A/C coil. I wouldn't have done the same thing with baseboard since there would have been no wa to get rid of the condensation.
