I have a 2003 Monaco Exec 40 ft. The Aqua hot was not warming the living area or the bathroom, the bedroom was toasty warm. Took it in and they found one leaking pump out of 3 pumps. They replaced it ...
I'm confused - I thought these were hot water pumped radiant systems but now I'm seeing comments about fans. Are there fans in each zone that blow air out of registers? I had been picturing in-floor radiant systems like I see in houses.
