hooking up an Aquabooster to the tankless? This way, the boiler would only fire when the Aquabooster tank called for heat, or one of the heating zones called. It would eliminate a lot of your current stand-by losses.

    tankless

    Currently I have a hot water boiler with a domestic hot water coil. Would there be any benefit to using a reaini tankless hot water heater? As the cost of oil continues to rise I am more and more concerned about the up coming years heating bills. I already have LP Gas but I am wondering if the cost will outweigh the initial installation. Any thoughts? Thanks. Mark.

    I was thinking more along the lines of disconecting the boiler all together and just using the tankless for all of our hot water needs. Will this result in a net savings or am I just chasing my tail....propane vs oil and the instalation cost.....might be a close call......maybe we should just buy the kids some warm sweaters.....Mark

    First check

    the cost per BTU of oil vs. propane. In most areas propane is considerably more expensive per BTU than oil.

    Then there's the safety issue. Propane is heavier than air, and can accumulate on a basement floor, just waiting for something to ignite it. Some Codes prohibit propane equipment in basements for this reason.

    Also, if you're thinking about using a tankless to run the heating system and also provide hot faucet water, you MUST separate the two so they will never mix. Combined systems are breeding grounds for Legionella and other nasty things.

    Then you have to find a suitable place to vent the propane tankless. A unit big enough to handle the whole house needs some serious chimney capacity, or if thru-the-wall venting is used you might find there's no place for the vent that meets the manufacturer's specs or local Codes (distance from windows, snow accumulation levels and so on).

    Then you might find that the burner in this whole-house unit is so big, you need to run higher-capacity gas lines.

    Obviously you need to do some research here, to be sure you're making the right choice.
