    The crummy sheet metal baseboards housing fin-tube are designed to promote convective heat transfer, and are primarily convectors, not radiators, though low double-digit percentage of the heat...

    With seven zones why do they all have to be programmable? I suspect most would be fine with a "set and forget" approach at 55F until that zone is actually being used by the visitor-occupants.

    Most houses in FAIRBANKS AK have heat loads smaller than 50BTU/ft of conditioned space. I'm pretty sure the heat load of a 2200' house in Warwick NY won't be over 50K unless there is unsual amounts...

    A heat pump water heater completely separate from the oil boiler will be a cheaper way to heat hot water, and would allow you to run the boiler at a lower and more efficient temperature. With most...

    Only go with an indirect if it's gas fired. Heating oil & propane are too expensive to use/waste at 50-60% efficiency, with pricing more volatile than electricity.

    I couldn't find an ASTM E96 vapor permenance number in the spec. Many things that are waterproof to liquid water are still somewhat permeable to water vapor (take rigid foam insulation, for...

    If the boiler is gas-fired it's probably better overall to install an "indirect" fired tank using the boiler's heating output to heat the water in the tank (which has an internal heat exchanger), and...

    The are all custom parts and I'm not sure if they have regional distribution near you, but you can get 1- day shipping from their CA location.

    The System 2K control algorithms are well integrated to the unit, but likely to come in at $10K+ for an installed price, and wouldn't likely meet the pay-off in under 10 years criteria. Yes, it...

    You can do a bucket-test at your shower head to figure the gpm, and measure the incoming water temp at a tap nearest the point of entry to the house. At 8.34 lbs/gallon and 2 gpm with a 60F rise...

    The high retail cost at Home Depot is why you buy them at EFI instead, where a 3" x 60" costs $525, and a 4" x 48" is $577, either of which have better than 50% energy return at 2.5gpm under the...
