The reason you need to cut off power when replacing a thermostat is to prevent the wires from touching each other in the process of disconnecting and reconnecting all of them. Assuming it is using 24VAC control (you need to measure it to make sure it's not high voltage), you are not in danger of getting shocked, but if the wrong wires touch each other, it ...

You said inverter generator , these are usually much better than the type I use, with the old fashion alternator and voltage control. I power my TV’s and microwave refrigerator, furnace and well pump with mine and have done this for over 20 years without knowingly killing anything. I have been on generator power up to 2 weeks and loose power for at least a ...

Page 16 of the boiler installation guide PDF (Section 7.3 - Ventilation of Compartments) points out that no air vents are required in cupboards or compartments with your boiler. This is because although the boiler requires oxygen in order to burn the gas correctly, your boiler has a double walled (balanced) flue and takes in all the air it needs through the ...

If you locate the make and model of your boiler, and look it up on the internet, there will most certainly be an install guide available on the makers website. If you posted a picture of the label on your question if you have had difficulty in finding what I mentioned, we can look it up for you. The guidelines listed by the maker MUST be followed, there is ...

That baseboard radiation will work great on a 2 pipe steam system or a forced hot water heating system but is not recommended for use on a 1 pipe steam system.

Since tenants are involved, you'll need to do this right If you were owner-occupying a zoned single-family dwelling, then taking shortcuts in the interest of expediency would be an acceptable way to get rough estimates of zone energy usage for your own uses. However, you're not in that situation; you're dealing with tenants instead, which brings real ...

Look up the installation manual for the HS Tarm OT-70. In the 70s, these were hooked up to pressurized hydronic systems. To prevent boiler explosions, they were required to be installed with at least one zone having an air-conditioner like thermostat -- above a certain temp, the zone opens, and the entire set of radiators works to radiate heat. It isn't ...

In the 70’s we did install heat loops in wood stoves , they were open tank pumped units. Why open tank pumped? The system had to be open to prevent a pressurized system because pressurized systems are boilers and boilers are regulated, require steam certified pipe fitters. The systems we used had check valves that allowed water in the heated tank as it was ...

A woodstove would never be connected to a cylinder in such a fashion. The only use for the thermostatic valve is to control the output of the hot water tank to the user and a common setting is 46 degrees C. The hot out pipe of the woodstove should have the combined P&T valve fitted with an expansion pressure vessel to allow for the normal water ...

Is there any other place where you could use this high temperature water? Is this for a residential or commercial building? What is the maximum allowable water temp in the cylinder? An alternate to dumping the hot water through a pressure and/or temperature device would be to install a fan coil to reduce the excess water temperature and not introduce any ...

No, that's not a valid way to determine energy usage. With a hot water system you need to know three things: The flow rate of the water The temperature drop of the water through the loop The time over which this happens With these 3 you can determine the energy "lost" in the loop which presumably went into your rooms. The "magic" formula you'll need is: ...

It might be dangerous to assume that each pump delivers the same flow to each zone so you may need more than the run-time for an accurate set of results. So pump run time, flow rate and the temperature drop of the fluid delivering the heat (ie supply and return temperature). You could then compare with the boiler hot water output using the run-time of the ...
