Home heating system replacement--any advice on selection would be appreciated
I am looking for advice on replacing a failing heating system in residential home in Southern NH. Here are the details:
30 year old oil fired boiler with tankless coil for DHW.
115,000 btu
appx 3000 sqft--and tight
consumes only about 600 gallons of oil a year
The distribution system is forced hot water base board (about 210 linear feet of finned), 4 zones that will not be replaced.
I am trying to decide:
1 Does it make sense to switch to propane
--cost effective due to the added cost of need for chimney liner?
--lower maintenance costs
--Higher efficiencies (offset by lower btu output
2 direct vent condensing boiler--there is no low temp demand such as radient flooring
3 which brand would be best suited/best bang for the buck
--Buderus and Viessman have good reputation and higher claimed AFEU, but are they worth the premium price
I would also like to add outdoor reset controls and an indirect HW tank.
Looking for a cost effective solution, mainly between oil and Propane, and between brands/models. which ones have better realized efficiencies, less service issues, cost effectiveness, etc.
I welcome all advice from experienced professionals
