Adjust the boiler so that the output flow temperature is 55°C (or 130°F) or lower. See if your house remains comfortable on the coldest day you expect to have.

Adjust the boiler so that the output flow temperature is 55°C (or 130°F) or lower. See if your house remains comfortable on the coldest day you expect to have.
Note that if you have a boiler not designed to operate with condensing flue gases, this test will eventually damage the boiler [over the course of months, not hours]. If you have a plastic exhaust pipe on your current boiler, you're totally fine to do this.

- Kon-Peki 3y agoI do appreciate the writeup, but I feel as though there has to be a better way :) In my area, the most common HVAC system is going to be a gas-fired forced-air furnace along with a central air conditioning system. What do you do there?
- sokoloff 3y agoAir to air heat pumps are a pretty straightforward retrofit there. (Including central units with reversing capability; heat pumps don’t have to be per-room minis.) In some ways, that style of central heat pump is less talked about because it’s usually a straightforward replacement. Ducts may need to be enlarged in heating-dominated climates though.
