Optimal Run Time for Boiler — Heating Help: The Wall

Feb 19, 2015 · If you run 1 CPH and require a 25% boiler percentage for the current ambient, the piping will be cooling for 45 minutes prior to the next start. That 2 minute time is going to increase. If you run 3 CPH and you require a 50% boiler percentage for the current ambient, the piping will be cooling for only 10 minutes. Now, your times are realistic.

What are the most efficient boilers of 2020? | The Eco Experts

Often the main reason for the expense is an inefficient boiler. Replacing an old boiler with a gas condensing model, or even a solar-powered system, may cost a bit more initially, but once installed they can be much cheaper to run. Installing an ethical, eco-friendly boiler is an ideal opportunity to both help the environment and save money.
