not a huge house maybe 2500sq ft. its a pretty large boiler system that was put in over 10 years ago. maybe they make them smaller and better on power now? mine is a closed loop fyiThis has me wondering. Is this a huge house? I mean, 10k sq ft? My neighbor has a house with 3 Truck garage (can park 3 semi-trucks inside) and he put in floor heating through out. I asked him about the power requirements and he said it all runs on a 20 amp breaker. About 6 amps (7 amp start up) for the boiler and 3 amps per circulating pump, which he has 3. Two for the garage and 1 for the house.
His installation was cheap since that is what he does.
He did say it doesn't save him any money over normal garage style heaters, but it is nice because the floor is warm.
