our floor heating is an open system not under any pressure just gravity and pumped through the floors with an armstong pump. We are going to put a new bigger BTU boiler in and the contractor wants to pressurize it slightly so its a closed system. The only problem is i still have one bay that...
this is a call out to all car wash owners as to how big is your boiler for floor heating using pex or steel in floor. we have a 3 bay wash using a weil and mclein 105000 BTU boiler with pex in the floor. Im wondering if it is a bit underpowered. HOW BIG IS YOUR BOILER IN OUTPUT per bay or...
ive been checking around and alot of car washes still have open systems running with no problem. i know of one car wash , 3 bay had the same problem as myself in that the bays were freezing up . so this fellow flushed out the system and recharged it with less percentage propanol and it worked...
the system is open to the air. the glycol flows into a box and is pumped via the pump through the bays. the older carwashes were made this way, no pressure. the new car washes apparently are made with 10 to 15 pounds of pressure and its sealed so not to allow air into the system.
I have researching the idea of pressurizing the glycol in the floor heating system. Presently my floor heat is not pressurized only gravity with a bit of pressure from the pump but it is an open system prone to getting air and the odd time cavitating at the pump. if i pressurized the system...
the pump pulls the cooler water from the bays into the boiler just under the influence of gravity. It isnt under pressure at all like my system at home or some car washes. Im wondering if it will work better under a bit of pressure? right now there is a 6" pvc pipe resevoir above the pump...
the floors are out of the wind but my doors could be insulated to bring up the temps a bit. summertime its a drive through car wash and in summer we take down our wooden doors. Our total SQ is 1360. heated by a Weil and Mclean 105000 BTU output boiler. From what im seeing i think we use...
This past 2 months our floor heat will not keep up with the ice build up. Im wondering if there is an air lock somewhere. our system had propolene glycol in it but ive been adding ethylene glycol at 50/50 so ive diluted it to 30%. Our boiler is 105000 btu per hour. im wondering if the boiler...
One thing to keep in mind is you need volume of heat in the floor and the bigger the tubes the more heat you can get to the floor to do the job. Never put a tubing system in that is smaller than 5/8" and pesonally i wouldnt go below 3/4". We had a company put in 1/2" tubing and when it goes...
the original floor was steel and worked terrific but 2 years ago we tore it up and replaced it. The company used 1/2" plastic with 2 feeder lines going into the bay. the bottom line is when the temps go below -8 the bay freezes up and you wouldnt know there is a coil in the floor. we have...
