Re: BTU kW Sizing - I am pretty sure this is a stupid question but you decide!
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
Re: Steer me away from potential disaster?... (Heat transfer plate install in Europe)
my experience with self drilling screws is that they just make a hold bigger than the threads in solid materials, i have only had them work in sheetmetal. there are screws with deep, very coarse threads for softer materials.

Re: Steer me away from potential disaster?... (Heat transfer plate install in Europe)
Maybe contact a fastener company and explain what you are screwing in to. There are thousands of specific screws available. Here is one big name example.

Something with a short drill point may help?

Re: Connecting AC to Hydronic System
Ok thank you for seeing that, yes I completely agree. If I don't correct it now, it will be a headache next winter.
That being said I apologize for having an older pic there. That brown wire actually the wire running to the strap-on aquastat previously. It wasn't terminating at the strap-on, the 2 wires were just connected together. So the strap-on and that wire were removed. The white wire behind it is actually the wire that runs to the T-T of the Taco.
I have that T-T wire connected like your diagram above, will that be fine?
Re: leaky sink trap connection
Hard to say without watching the video. As much as I love an 18 gauge p-trap, the cheap, plastic ones go together much easier and seem to last longer.
