Our 1900 house had an old boiler system (I think it was water, but couldn't promise) anyway, the boiler itself was rusted out so we got rid of it but kept the radiators for the look. Meanwhile I've been investigating alternatives to the traditional boiler heat system such as using Pex tubing to provise radiant heat all over the first floor. Our house has the original hardwoods throughout, so a couple of estimators have said that we couldn't use this type of heat w/ our floors. However, I have seen other on-line posts accompanied to this site stating to the contrary. Any thoughts who is correct? And suggestions?
