Re: Baxi Luna
They offered me a parts account a couple years ago and had parts for really old units that a customer of mine was working on. This was several years ago I don't have emails left from them so prior to 2020. If they left the market they still have a number to call and try anyway! They still have reps too

Re: BTU kW Sizing - I am pretty sure this is a stupid question but you decide!
If you have staple up or suspended tube for the upper floor you may indeed need that higher SWT. Or carpeted floors drive up the SWT requirement.
A room by room load calc would tell. But you already know what it takes.
Although floor heat and forced air behave much differently, A large hydronic coil in the air handler could allow you some heating supplement at low SWT, 120 ish. And some cooling.
Is peak efficiency the main driver in your decisions?

Re: Yearly prepaid heating oil contract a good idea?
There's another risk besides the price of fuel changing.
An oil company that was in our area for many many years went out of business. From what I saw anyone that had prepaid them was up a creek.
I don't know what the chances of that happening are but apparently it is a possibility.

With air to water you never want to be mixing water down, it is a big hit in COP. You want your emitters to run at the temperature the AWHP puts out. Baseboards are not the best supplement as they don't put at all that much heat per foot at the low SWT. If you need more heat, the best option is a low temperature panel rads.
As for cooling, the idea of using the air to water unit sounds good until you dig into the details. The bits you need are expensive and EVERYTHING not properly insulated will sweat. Since there is an extra conversion, efficiency isn't all that great. About the only good thing about is you can micro zone. I would stick to regular air to air units for cooling.

Re: Vent placement in home 2-pipe steam heat system
@pacoit , can you get a close-up of the emblem on the side of the shutoff valve? This may help us ID your system. Also, where are you located?
Re: Help identifying contactor terminals
And the MFgs always bring the power in the bottom which is wrong.
And they use a single pole contactor where it should be a two pole…….that must save them at least $.10
They rail about safety and then violate what we were taught.
But, they get it passed by the know nothings at UL so it has nothing to do with the electric code.
Re: Whats involved in a refrigerant line repair
Yeah it takes a lot longer than you think to repair refrigerant lines. If this company is doing the work at no charge based on your past business with them it seems like they are probably a good one to stick with.

Re: Whats involved in a refrigerant line repair
Let them do their job. They sound like a good service provider.
Tipping the workers is always appreciated. $10 or 20 each.

Re: Whats involved in a refrigerant line repair
no they’re not charging me for this, though they could as refrigerant line repair is excluded in the contract language.
They found the leak at a joint in a copper line just outside the condenser. This is the second time that joint has leaked. Guy said the first repair looked messy which is why they’re taking care of this one no charge. They didn’t charge me the first time either.
i don’t think they have recharged the system beyond these two joint leaks
