Hydronic Heating

Posts Tagged ‘hydronic heating system’

I plan on making a solar water heater, for a hydronic heating system. Would it be efficient to take a satellite dish (like a dish network or direct tv), attach small mirrors on the face of it to concentrate the sun’s heat? I would feed flexible copper tubing through the arm, out to where the receiver would normally be, and twist it around a few times and then bring it back through the arm. I would pump water through the tubing, which would would then circulate through the house and back to the concentrator. I would more than likely put more than one of these in series with each other.
the glass covered box would work, but it wouldn’t be as fun to build, but I’m wondering how efficiently the dish idea would work.

I want to purge my hydronic heating system by fast-filling it and draining it simultaneously. I need to cool my cast iron boiler so I don’t crack it and completely ruin my day. The temperature of the water main is around 40°, and I am wondering how cold the boiler has to get. I have read one manual that recommends a temperature change of no more than 40°, which would make the target temperature 80°F, but the same manual also says that this rule is sometimes changed to 20° temperature change

OK, handymen, its a 1951 American Standard Arcoliner. Whaddayathink?
Here’s that manual I found http://www.smithboiler.com/modules/news/upload/%7B27A60D51-C198-453F-BAD7-67A71B1D4176%7D_Thermal_Shock_Publication.pdf
By purge I mean purge air bubbles
The idea here is not to change the water, necessarily. The point is to use the fast fill to shoot water through the lines, hopefully driving out trapped air, which is hampering the efficiency of the heat transfer at the radiators.

To reiterate, the actual question is: In your experience, how much difference can there be between the temperature of the boiler and the temperature of incoming water before you risk cracking the cast iron?

Hi,

I just bought a new house, and I want to change the old analong thermostat to a digital one. The heating system is a hydronic heating system with a big blower (similar to a gas furnace system) and an AC condenser outside.

I was looking at the different wiring scenarios in the instruction manual for my new digital thermostat and it mentions a single stage heat pump.

Is a hydronic system actually a single stage heat pump?
Would you wire a hydronic system different than a regular gas furnace system?

I have a hydronic heating system (with two zones) in my house and the control wiring looks very questionalbe, I recently purchased the house and I think the previous owner tried to by-pass or repair it, at any rate there are wiring nuts and electrical tape everywhere and it does not look professional at all. I want to start for the beginning and see if can check the system out. To do that I need to start with a controls wiring diagram, does anyone know where I can find that info on the web?
