Is this forum for any specific type of HVAC system? I have a forced hot water oil fired boiler with tankless water heater. The house has 3 zones each with it's own circulating pump. It was installed and maintained by a local oil dealer for over 30 years. The only DIY thing I did was add a wireless thermostat because one of the zones did not heat the rooms (kitchen, dining, living) ok with one thermostat position. I move it around with me so it's 70 wherever I am.
Is this the type of system that your PROs have experience with?
