Re: Insulation for steam pipes in basement

1"wall fiberglass and PVC fitting covers. Buy the thumbtacks with the pvc covers. Thumbtacks have little barbs to hold them in place skip the tape it makes a mess.

Trick: put the thumbtacks in the PVC fitting before you put the fitting on the pipe

Re: Do Energy Kinetics Ascent Boilers require special Thermostats?

Good morning,

The Energy Kinetics Ascent boiler can be controlled by a simple day night programable thermostat or with a Wi-Fi thermostat. Whichever suits you. We do not need special communicating thermostats.

Where do the valves on the radiant manifold go to?
I 'm not sure this is the best design but I like to put the HX potable water heat at the bottom of the tank and let the heat rise to the top of the tank until the bottom thermostat shuts off the pump. If needed the 220V top element and thermostat can be there in the event the HX can't keep up and the top of the tank gets cold water that high, while the bottom thermostat keeps operating the HX heated water. The top and bottom thermostats are wired with different voltages and the bottom electric element is abandoned.
I think the HX flow needs to be reversed on one side for best results
Need Circulator to move water from Mix to the radiant floor
Best practice is to pump away from expansion tank for air control
What is the model number of the thermostatically controlled valves? Are they just regular 24v. electric zone valves?

I think this is close to @hot_rod Bob's first drawing.

I hope this helps.

Re: Professional opinions please

a hydraulic separator is a great option. It gives you air, dirt, magnetic, and hydraulic separation in one device. Quick and simple to pipe.

I added a HX pump, I’m not sure how or when that circuit is operated? Does it just maintain the hw tank temperature?Expansion tank connects at either of the lower sep connections
