Re: Air to Water Heat Pumps
That's a system I would not consider on "The Isle of Long". Unless there is a fuel boiler back up. ..

Unless you purchase a lot of LP Oil is generally cheaper.

Re: New Propane Boiler Options
I think HPWH have a long way to go to be reliable. To me they are an expensive throw away appliance.
Who are you going to call when you have a refrigeration issue? The MFG will say scrap it its not worth fixing. The plumber who installed it probably does not know refrigeration. Is an HVAC company going to want to bother with it?
Unless it is a simple fix the cost of replacing a compressor or the controls will exceed the appliance value.
And guess what, any energy you saved is GONE. Quality is not ther.
I can't even find a window unit that will last.
Re: Now ya see why PVC on mod con flue is not a good idea
I just want to mention that when PVC is solvent welded, you're using a solvent like acetone or MEK to literally melt the plastic. Once the solvent evaporates it leaves the PVC solid again and in literally one piece rather than two.
I'm not sure that even counts as glue, technically.
If memory serves PVC cement is solvent with some pvc mixed into it to act as filler material.

Re: Now ya see why PVC on mod con flue is not a good idea
In my opinion that PVC was not properly solvent welded, that isn't the materials fault it's the installers fault.
I don't think that even get hot warm, look at the barcode label on the coupler.
B vents can pull apart easily if they're not twisted and locked together correctly.
Single wall galvanized pipe can pull apart easy if there isn't the proper 3 screws per joint.

Re: Now ya see why PVC on mod con flue is not a good idea
Obviously from what we have learned PVC for flues is not a good idea unless approved and the only one I know that is is Ipex,
It looks like the glue and primer is good but who knows.
Dis they sand the fittings and pipe?
was the glue old?
did they let the primer dry tooo long b4 gluing?
It doesn't look like the PVC was overheated, it usually turns brownish.
Re: Old HP system failed: new refrigerant choice? new equipment reliability?
I am at an age where the cost of labor and material seems way out of wack.
But, I also ran my own business for 8 years back in the 80s-90s. Things add up real fast.
I just went through this myself. I needed a new storm door which an Anderson is about $400. Got a quote from a contractor who wanted $1100. I thought it was really high so I did it myself.
- Go to lumberyard and order door & wait 10 days for it to show up.
- Remove tools & stuff from truck to make room for door. (truck has a truck cap) and lug tools to basement.
- Pick up door at lumberyard
- Remove old door
- Install new door
- Cut up old door and take to metal scrap yard. $15.50
- Put tools back in truck, lug them up from basement.
Yeah maybe a contractor would not have to go through all those steps.
But he has a truck, tools, liability insurance, workers comp, overhead , profit and truck insurance.
Somebody has to pay for that stuff.
$1100. was probably not an unreasonable price
No one should bash a contractors price without analyzing it.
Try it yourself.
Re: Replacing large steel pipes going to/from hot water boiler to cast iron radiators with PEX
Think about how you're going to join on to the riser before you cut it and where you have space to cut out the remnants of a pipe or cut off a fitting by scoring and splitting or shattering it if it doesn't unscrew, make sure you are working someplace where you have room to work.

Re: Radiant heating pump relay
Actuators with end switches on each manifold port would give you complete control. If multiple loops go to one zone, connect thje actuators to one t-stat.
You need a ZVC control and actuators for the manifold
