Installing DS 1100 Aqua Gem and gravity flow radiant floor heat.

I assume you mean how long it would take to get the water moving... No clue. There's a lot of variables to that.

It takes a while to get a gravity set up up to temp and pressurized. Did you get a permit for this? You should to protect your homeowners insurance. Code Enforcement will love this.

There are not a lot of variables; getting the vertical plumbing right to flow at 170 degrees which prevents boil over 170 degrees which is the temperature required for the water to travel up a vertical standpipe to the open to air expansion tank and then flow downward to the radiators without bleeding them with a top fed system.

A bottom fed system requires 170 degree water which also travels up to an open to air expansion tank and then flows downward and requires each radiator to be bled of air to permit the water to flow to the basement through the radiators.

Did this happen? Does it work?

Yes it did happen, and it does work.

House is 70 degrees.
Water temperature hasn't reached over 135 degrees. And not less than 95 degrees.
I burn an average of 50lbs of anthracite nut coal every 30 hrs. Somewhere around 25,000 btus/ hr. Numbers are average for the past month.

Interesting... do you know if it’s 135 at the farthest zone or just 135 out of the outlet? What’s your return temp?

Chancey P. · Post by **Chancey P.** » Mon. Dec. 28, 2020 5:33 pm

That's at the supply. But today I'm only at 115. I adjust it based on weather/needs. Return temp is 25- 30 degrees cooler. Return temp varies as well. There is no thermostatic valve the Samson damper control is what I use. The water is always moving.

Indeed! What are the dimensions (as nominal ID) of the supply and return headers, and the floor heating PEX?

EDIT: I read back yo the start and all of this is detailed there.

For 50 Lbs. of coal feed every 30 hours I see this at about 20,500 BTUH as input, and about 14,500 BTUH as output (the actual BTU's heating your house). On the very coldest days of the year you may see this triple.

How many sq-ft of floorspace are you heating? New construction? Well insulated? Single story?
