Can you give me the pros & cons of combining RFH on a first floor slab of a cape (NE area) with second floor baseboard heat (ala Runtal). I'm hoping to allow individual 2nd floor bedrooms easier control of heat without the need for a more complex RFH control system with all its tubing.

    These combo systems work well , and you can save some money by useing outdoor rest control ,tekmar or danfoss ecl control , but if you want to save money over the long run pure radiant works best , ( The rule is for every 3 F you turn down the boiler you save 1% in energy ) doesnt sound like a lot but if you can turn down the boiler 40 F that saves about 13% in energy , keep asking questions till you get your answers NRon

    Pros and Cons

    If you really are hoping to have more individual control and simplicity then perhaps you should consider all rads and a liberal use of TRVs on them. Otherwise, you have a dual temp system which adds to the copmplexity. If you decide that you want to go rads, oversize them to keep your temps down and then you can take full advantage of a condensing boiler. The pros of this are that you have a system that can be easily maintained over its entire life, requires minimal electrical consumption for heat circulation/controls and allows you to zone very inexpensively. The cons are that you lose the heat underfoot aspect (most noticable on tile floors although you could run some staple up to warm these areas at the system temp), you have to buy a lot of expensive rads that may get in the way and they add clutter to each room.
