We have been trained to think about energy efficiency best practices for buildings in terms of improving insulation. It’s an easy enough concept to understand because we can experience heat loss personally. For example, on a cold day, if you don’t have a thick enough coat, you feel cold. It follows that more insulation will keep us warmer in colder weather. However, we often overlook other influences that affect energy efficiency, such as air leakage.

In a previous blog post, I recommended switching your fossil fuel-burning appliances over to heat pumps to heat your building. That recommendation still stands for everyone who has mid and low energy efficiency furnaces and boilers and anyone whose heating appliance is older than 25 years. I recently spoke with a congregation whose heating system predates their building from 1962 (it was used and donated to them). Their heating contractor estimates that it is currently operating at 15% efficiency! So keep that in mind folks.
But what if you have a pretty new boiler, for example, and still want to maximize efficiency? Is there anything you can do? Yes, there is! When we look at radiator systems with all the various parts, there are numerous opportunities to improve efficiencies.
