A year ago we bought our 1927 house in the Boston area. We have cast-iron hot water radiators and installed a high efficiency boiler with indirect hot water heater last year. We are planning to install conventional ducts for central air. It turns out that for another $1,000 we can also remove our radiators and convert to hydro-air. Should we do it?
Here's my list of pro /cons. Any others we didn't think of?
- Will get heat in all bathrooms (currently we don't have a radiators in the 1st floor half bath and the radiators in the 2nd floor baths do not seem to heat up)
- Give space for better furniture placement
- When we return home from ski trips the heat will come on quicker (now it takes an hour for the house to become warm)
- Hope the temperature will be more even, now when the radiators heat up their hold on to the heat which makes the house warmer then we'd like
- Solve the heat issue when plan for a kitchen remodel (the radiator is built in wall which we plan to remove)
- Removing radiator pipes in the basement will allow us to finish the space with good headroom
- Adding zones - now we are on one zone and with the hydro-air we are planning to get two systems with one from basement to first floor and the other in attic to second and third floor
- Dryer air (with a humidifier, does hydro-air feel more dry than radiators?)
- Noise (should we assume it's noisier?)
- We have a system that works and concerned about installing something that doesn't work for some reason
- Carpentry work - we'll have to fix the floor and paint (something we plan to do on our own and we already have all the paint)
What are your thoughts regarding hydro-air from the perspective of comfort, cost of operating, and maintenance? Thanks!
