1920s brick veneer Tudor
Good morning. I bought a 3400 sqft Tudor home built in 1927. As is normal with many homes this old, their are many idiosyncrasies (to say the least). My biggest issue at the moment is comfortability. This is a 3 story house where the attic was finished into the master bedroom (3rd floor) and the second floor has all of the other bedrooms. The house has two cast iron boilers and two Ac systems. There are lots of issues with the heating zones. When they created the addition they added all copper fin baseboard heat. However, the left the original cast iron radiators in the second floor bedrooms and on the first floor. The second floor also has a 1000sqft great room with all baseboard heat. The boiler that controls the first floor radiators also controls the second floor bedroom radiators. The second boiler controls the baseboard radiators in the kitchen on he first floor as well as the second floor greatroom and the 3rd floor master. This created issues with having to run both boiler to effectively and evenly heat certain areas of the house.
A solution would be to properly zone everything but with the mishmash of copper fin and cast iron radiators, chattering relays and I’m convinced that the boilers are oversized, so a system overhaul is likely needed. I have read enough articles on hydronic heating to know that industry professionals prefer hydronic to forced air.
I am really considering forced air for the following reasons:
1. new system more affordable than new boiler system.
2. I can have a properly functioning humidification system.
3. Free up valuable floor and ceiling space in basement (boiler still utilizing old gravity piping some of which are 4” in diameter.
4. Forced air probably more appealing to a wide range of possible future home buyers.
My major concern is that forced air will heat the house as well plus after I remove all of the radiators there is no going back obviously.
A cost comparison between forced air and a new hydronic system would also provide clarity I guess. The main issue is finding a qualified HVAC pro in my area that can do the proper load calculations and who has experience with boiler AND furnaces.
One other thing is that the house is not insulated so I’m trying to determine if that would be advantageous and if so, blown in cellulose in an old brick veneer?
i knownthis a lot of rambling. I guess in the end it would be ideal to find a local (chicago area) consultant that could see the house. Absent that situation can anyone way in on replacing a 20 year old double cast iron boiler and AC system with a high efficiency forced air system? I would also appreciate comments on insulating an old brick veneer house given I have already replaced windows, doors and there is no attic to lay insulation. Thanks!!
