OK Mike, Then it sounds like the electric mats aren't as bad as I thought. Are you just using them as a comfort heat source and not a primary heat source? Are they thermostatically controlled or do you turn them on and off when you want the heat?
I've been looking at hydronic for a primary heat source on the first floor of my house. -- Blue skies. Dan Rossi Carnegie Mellon University. E-Mail: d...@andrew.cmu.edu Tel: (412) 268-9081
