    This is typical spec builder garbage. This is just 1 of many surprises the builder has hiding behind walls. Drywall and in this case, brick veneer, hides a lot of sins/sloppy work. 90% of ...

    Peter, There are lots of skilled masons out there. Some of the best are honored at the annual Spec Mix Bricklayer 500 competition in Las Vegas. Here is a news report of a recent event:

    Dana, Right. Except my old-fashioned wood stove (which heats my whole house), cost me only $100 when I bought it. (Used, of course.) Just saying. It sounds like David Goodyear's system ...

    Only people I know that are building >3,500 sqft are millionaires who don't care if they pay a $400 per month utility bill. They have $$ to burn. I would rather build < 2,000 sqft and build it ...

    Being able to fire the wood boiler at it's optimum combustion efficiency, storing the heat for later is the right way to do it, especially at your very low average loads. A wood boiler can ...

    In 2017, the average (mean) size of a new single-family home was 2,571 square feet. The median size was 2,371 square feet. That means that half of all new homes built in the U.S. measure less ...

    Perhaps for a larger builder, they might need to build that large to feel like a custom builder. But there is still demand for custom-built, and well-built homes in the sub-3000 sf range. Not ...

    As usual, informative. Dana makes some good points. So all in all it seems that my heating system has generated some discussion. I am happy about this because I get to hear about things that ...

    Jared, I'm not sure there is a "best" way. The above-grade portion (the portion with stud walls) is insulated the same way as any above-grade wall. The concrete portion of the wall is ...

    If it's all inside of conditioned space the distribution losses are still heating the house, just not the particular radiator or zone that was actively using the hot water. They are NOT losses, ...

    Jared, Well, if he's still there, the easiest way would be to tell the spray foam guy in the photo to aim his wand at the walls. .

    What is the best way to insulate my basement wall? (picture attached)
  • Jon R | Jun 19,2018 02:19 PM EDT
    Evidently they make a "wall box" to house the AAV - making is accessible and at the right height.
  • David Goodyear | Jun 19,2018 02:10 PM EDT
    my main reason for the reset is that the water in the tank can easily hit 80C, mixing it down using some return water made sense at the time for moving low temperature water. Its also much safer ...
  • Dana Dorsett | Jun 19,2018 02:07 PM EDT
    DOH! Martin, that's right, it's the source fuel heat. (I should be more careful!) So the highest possible implied load example (75% combustion efficiency wood-burner) would be 0.75 x 105,000 ...
  • Jon R | Jun 19,2018 02:01 PM EDT
    A better calculation would be if the greater heat (btu) misdirection (not losses) from higher temp insulated distribution pipes is enough to worry about. A TRV modulates. Ie, it doesn't cycle ...

    Thank you for explaining Martin, and I appreciate all of the time you've put into this great resource. I was mistaken on my original recollection. The discussion was indeed on exterior moisture ...
  • Trevor Lambert | Jun 19,2018 01:32 PM EDT
    The requirement for being accessible and above the flood rim level is direct from the product installation manual. Even if the code doesn't require it, it only makes sense to follow. Just imagine ...

    Thanks Martin for your response! I’ll pass on what you said to the property manager. Sorry for the delay in responding, dealing with health problems
  • David Goodyear | Jun 19,2018 01:27 PM EDT
    I think the pumping costs are small compared to the total heating costs. The losses can be high through the distribution lines since the R-values are typically only about R-3 or R-4 for pipe ...
