Programmable Thermostat for boiler zones
We just bought a walkout ranch that has a boiler and my wife wondered if we could install a programable thermostat. There are three heating zones; downstairs, bedrooms (3), living/dining rooms & kitchen. The last two are on the upper level and we have the BR zone set at the minimum heat. The house is empty most of the day. Would each of the zones need to have its own programmable thermostat? And would it actually save energy?
