Re: Steer me away from potential disaster?... (Heat transfer plate install in Europe)
AMAZING personal insight - as always.
Will ask supplier about slightly larger PEX into plate.
Will try screw into the sample GIFAfloor that I have now.
Think the bigger challenge will get screws to quickly/easily tap into the gypsum fiberboard. May need to indent with 9d nail or equivalent to create a crater in board for screws (hope to avoid these extra steps!). With drywall, I know it is easy to get screws started because of easy for screws to pierce paper surface…
Asked the HVAC guy to calculate heat load. Dragging his feat so far… But is complete interior renovation (only 4 outside walls at the moment) and rebuilt to “Swiss standards” in terms of envelope insulation, triple pane windows, all new exterior doors, etc. So shouldn’t be a heat-loss-prone building. About 1400 sq ft with low ceilings, so not a massive area or volume to heat. All that gives some confidence that relatively small, relatively tight, relatively well-insulated.
Only major variable would spacing of plates. Aiming for 8” centers…
FANTASTIC example from your drywall ceiling. Ceiling drywall would be 5/8” thick. And not as dense / holdable as gypsum fiberboard. But - as you said - the weight of plate and PEX in minimal. And there is nothing “pulling” on it after installation.
Great, relevant, and encouraging example Bob! Very much appreciated!!! 😎💪👍

Re: Yearly prepaid heating oil contract a good idea?
I looked into the Green Energy Consumers Alliance. It would be automatic delivery and tied to the wholesale price of oil. It is currently less than I am paying for the cash price, so I signed up with the cooperative for a year. Thanks again. I appreciate the info.

Re: Beckett Oil Burner
HVACNUT - I asked the question because I want to keep some parts on hand for my house. For many years I worked as a plumber installing boilers and heating systems, now retired. Awhile ago I attended a trade school program specifically for oil burners learning maintenance and trouble shooting procedures. I have a house with a pretty new Peerless Boiler with a Beckett burner, I've decided to take care of it myself.
Thank you for all those that have contributed to my question. Very usefull

Re: Connecting AC to Hydronic System
what controls the taco zone control?
that t-t is designed to control a boiler when the zone is calling, it closes t-t on a heat call or a valve end switch depending on how it is set up.

Re: Connecting AC to Hydronic System
Doesn't the air handler have a transformer and relay to control the blower? G and Y and Rc from the t-stat should connect to the air handler and the contactor in the condenser should connect to Y and C in the air handler.

Re: Connecting AC to Hydronic System
Or do you have a hydroair coil in the air handler? Old systems g on the t-stat called the blower on high which is what you need for ac and y was just a junction point to connect the t-stat and condenser contactor. In newer systems y turns the blower on high, so you'd need a second relay for y if you don't have a control in the air handler to do a high blower call with g or y.

Re: Connecting AC to Hydronic System
Every part in that control box is easily replaceable and a standard part.
What is what you've labeled T-T? normally it is a control to a boiler that turns the boiler on when you short the terminals. Is it controlling a relay that shorts t-t in your case?(you need to make sure this is correct)
the easiest way to add cooling to what you have is probably to add a second relay that is controlled by y from the t-stat, use that relay to power the cooling speed of the blower, and connect the condenser contactor between c and y at the air handler.

Re: Connecting AC to Hydronic System
What happened? Did this system ever work before? Or did you just buy this place?
Re: leaky sink trap connection
I FIND THAT IT DEPENDS ON HOW SERIOUS THE LEEK IS
Of course this one looks pretty serious.
