My house is a small one, three bedrooms, semi-open concept living/dining room, kitchen, bathroom, laundry room, about 1,300sqf, occupied by two adults.
Currently, the heat/hot water is provided by Triangle Tube Phase III boiler, with 30G HW tank in the boiler. The majority of heat is via seven cast iron radiators in zone 1, while zone 2 is single room with baseboard. The boiler is still in working condition, does not have major issues, nor did it have during the last 20 years. Minor issues here and there, but they remediated rather quickly.
The radiator in the kitchen need to go, due to the remodeling plans that brought up the question about the boiler. Should we update the boiler as well? We answered yes and started to have contractors giving us estimates. My question is more about sizing the modulating condensing boilers.
The Phase III is 120,000 BTU/hr and seems oversized to the size of the house. The first estimate received includes the IBC DC 33-160 combi-boiler natural gas boiler. That is a 160,000 BTU/hr unit, about 33% increase over the current one. I do not know much about sizing the boiler, but the estimate seems to move to the wrong direction.
If anything, shouldn’t the size of the new boiler be around 80-100K BTU/hr?
This is actually the first time I heard about IBC boilers. I do know that they made in Canada, but that is about all. Where does the quality of this boiler, where compared to others?
