Re: Old house heating: Steam radiators or forced air?
In one case, someone who was renovating an old house and hated forced-air. In others, we extended steam systems into additions, and we have two such projects in the pipeline now.
Re: Valve and Actuator ID
A few months ago I bought a Danfoss TRV valve without the sensor portion and it looks very similar. It had the "spline" on the brass portion like the one in your photo.
This is the link to the valve: https://www.supplyhouse.com/Danfoss-013G8020-3-4-Straight-Thermostatic-Radiator-Valve

Mitsubishi heatpump performance
Hi,
I have a Mitsubishi heatpump installed in a 100 m2 flat and I'm not sure if the performance it gives is ok.
Model is PUHZ-SHW80VAA/ZUBADAN . Right now weather is pretty ok 18-23 celsius and the heatpump is only dealing with hot water.
It says that for 10kWh consumed it produces 20kWh. Is that expected?
thanks

shout out to mad dog plumbing
i recently had @Mad Dog_2 plumbing come out to my home for a steam consultation. he inspected the system and gave me his recommendations on what to change/add. He drew them out with the pipe sizes and fitting etc. Im happy to report my system is running much happier now. If you need some input on your system I highly recommend him!

Take batteries out
One thing we all do but shouldn't is leave batteries in test equipment. I had a piece of electrical equipment that was only 11 months or so old a Klein Circuit Tracer. I pulled it out and have been debating weather to sell it or not. They are a little bit north of $200 new. Only used a couple of times.
i posted it on Marketplace and had a buyer for $100 within an hour or so. I never doubted it would work.
I fired it up and it won't power up so I thought batteries were dead. Pulled the back off and its all corroded.
I spent an hour cleaning it up, backing soda etc and dried it our good with a fan.
It's toast.
I guess the cheap China batteries it came with leaked all over the place.😕😕😕😕 Now I guess I will go check my other tools with batteries.
Re: Lennox S40 "Will start soon" message
sounds like the t-stat isn't being powered from the system while it is in a heat pump call so the battery/capacitor goes dead, it stops the hp call, the battery charges and it comes back on, sees that it needs to do a heat call, starts a heat call, the battery goes dead, the cycle starts over.
That is either because the installers didn't hook the common to the thermostat back up when they replaced the equipment, they possibly reversed the polarity of something, or for some reason it is dropping power to the t-stat while it is in a heat call.

Re: Oh boy...
That is sad….
And you wonder why the industry does not like NEST products on HVAC equipment.

Re: Boiler Pressure
Hey Paul, Call that person on the phone and tell them to dispute the charge on her credit card. The company that charged her card and didn't fix the problem did not earn the cost of the service call they charged to her card. Especially when the customer asked if the expansion tank was the cause of the problem and the company's technician dismissed that being the problem when it actually was the problem.
Give her my info and I'll help her drafr the complaint to the credit card company.
Re: dealing with twists in the pex on staple up
unless you have a hole , the self drilling, drill point screws tend to push the plate away from the floor
Two pneumatic tools that work, a coil roofing nail gun with 3/4” nails. Find cheap tools at pawn shops. These two Makitas were pawn shop nailers , they have worked well on many jobs
Or the heavy duty Senco SNS 45XP will shoot thru the extruded plates.
If you do drill the plates and screw get a self feed screws tool
I guess it just depends on how fast you want your go
A short piece of 1/2 copper tube is a good alignment tool, solder a tee and make a handle to push it in and out
