Boiler Running Costs in BC Explained
A condensing boiler's efficiency, your usage and gas rates determine running cost.
Knowing what affects your boiler's running cost helps you budget and save.
Efficiency is key
A 95% AFUE condensing boiler turns almost all the gas into heat; an old 70% unit wastes nearly a third.
Other factors
Your home's heat loss, thermostat habits and hot-water use all affect monthly running cost.
Key takeaways
- 95% AFUE minimizes waste
- Old units waste 25–30%
- Smart controls reduce usage
- Servicing keeps efficiency up
