My husband and I are die-hard TOH fans. We have had some problems related to labor troubles and inexperience on the part of our contractor. There is some fine tuning that remains to be done and we have even considered taking out our boiler and replacing it with a hot water heater. I'm sorry about your installation troubles.
Radiant heating is a simple system when installed by someone experienced.
There is a national association of radiant heating that has local chapters as well. Water left in heating pipes all summer and allowed to cool are breeding grounds for bacteria.
