I am moving into a house with oil-fired baseboard heating, and no central a/c. The boiler is on its last legs and will need to be replaced shortly (likely within a couple of years). I would like to replace the baseboard heating with radiant floor heating. I would like an alternative fuel other than oil, however, natural gas is not available in the area. I have access to install the radiant tubing from below for the first floor; however, I would like to avoid ripping up the finishes on the 2nd floor for the time being. I am wondering if I can install radiant heating on the first floor, and keep baseboard heat on the 2nd floor until I am ready to rip up the 2nd floor finish floor to install a sub-floor with grooves and metal panels for radiant tubes. I feel I could accomplish this if I simply replaced the boiler; however, I would like to utilize (potentially) a geothermal heat pump and/or solar hot water. I believe these methods would generate a high enough water temperature for radiant heat, but not for baseboard heating. What are my options? Is there a supplemental heat source that could heat the water from 115 to 160 cost effectively? I would appreciate any thoughts or recommendations. Thank you!
Keep baseboard heating for Heating season, and mini-splits for cooling. Otherwise, you can have both forced air for cooling, and boiler for heating, such as the case in my wife's grandmother's older home. It means running duct work if you want forced air, otherwise with mini-splits, you are just pulling electric & a lineset for the indoor units. Choose your evil.
