Re: Leaking valve on water tank

This ^^^^^. Before you go to the trouble of replacing it, which would be a bore, try fixing it — which might take a few minutes…

Re: Help Sizing A Multi-Zone Mini Split System - Minimum Capacity?

This was done by an HVAC guy, not me. I have to trust that he did it right.

Thanks a lot for that calculation, I gave it a shot earlier on when I think you posted it in another thread. Will have to see how mine compares to what you provided.

Yes, the 900 gallons is for the entire house and hot water for July 24 to July 25.

She also keeps the house rather cold (approx 63F, I think?).

So you're saying that the heat load I mentioned above is too high since you feel that 44K BTU/hr is right for the entire house? The HVAC guy also has another 35K for the downstairs which basically mirrors the upstairs except for the loft area.

The ceiling above the stairs is actually really quite low already. I'm about 6'3 and I am quite close to the ceiling as I go up/down the stairs so they're probably the requisite 6'8" you mentioned.

Not quite sure why because there's just the attic above and as I recall, it's just flat up there.

Re: OT What is this metal piece found in excavation?

it could be old lead sheathed uf

are there any older outbuildings that no longer have power?

lead sheathed uf was replaced with pvc uf in the 60's or so.

Re: COP & sizing question

If the home already has a fuel fired hydronic system, keep the boiler, modify the emitters if needed.

But installed cost of an A2whp is fairly $$

Re: Can someone explain this hydronic loop heating.

Will this be the correct fix? Remove the top baseboard and add an 1/8" bleeder.

Is the automatic bleeder reliable ? Or stick with the manual one ?

Thanks again for all the responses.

Re: I'm getting solar panels. I'll let you know how it goes in this discussion thread.

@ethicalpaul - re: "About the same price as a boiler install" - I'm over in NY, but probably not too far, and my 5KW array (after incentives) was a little cheaper than the boiler I had installed the year before. The array has continued to average around 500 kwh/month for the last 7 years (+/- 10% based on weather), which, as electricity prices have come close to doubling in the last 7 years, has had a substantially better financial return than my boiler.

Re: OT What is this metal piece found in excavation?

Is it lead jacketed or lead-sheathed wire cable / electrical cable ? If you are sure it is de-energized cut a bit off the end for a better (cleaner) inspection. Capture the chips from cutting.
