Ten years ago, I had a Wirsbo radiant floor heating system installed in a new house. The technology was new here in Oregon at the time, and it was the first installation done by the contractor, who had been trained by Wirsbo. The heat system and hot water for home use are all on the same system. The system includes a 30 gallon Polaris heater, AO Smith 119 gallon holding tank, Taco switching relays and a kazillion zones for my modest 2200 sq home. I want to change several things, and am looking for advice on how to proceed: 1) Separate the water going into the radiant floor system from the water I use at the sinks, etc. Our well water is high in mineral content and I believe the tubing imbedded in concrete throughout the house is building up mineral deposits that will eventually restrict water flow. We don't need the heat upstairs much at any time of the year since the kids moved out, and we don't heat the house at all during the summer months. 2) Calculate the size boiler I really need (I have seen references in other threads to a heat loss evaluation, but don't know how to do that). 3) Find a thermostat that works. The Wirsbo brand thermostats currently installed are finicky and inaccurate. I will have the work done by a professional, but need to know what I'm getting into before I hire someone to do the work. Thanks in advance for your advice.

I think that's what they're called :) We're putting in a new kitchen in a few weeks and I'm a little confused.... I know we need toe kick blower under one of the cabinets because the heater runs along the back wall (hot water radiators, oil heat). 1. The electrician and plumber should come in before the cabinet, correct? Do they have to know exactly where the cabinet is going or can they rough it in and we can move it? 2. does it replace the baseboard or attach to it? Any recommendations for brands? Should I just let my plumber order one? THanks!
