Who are you calling an old boiler?

Old heating systems are also extremely inefficient; they waste millions of pounds each year through heat escaping via the flue and from over-heating because of outdated or absent thermostats. Research by the Energy Savings Trust (EST) reveals that one third of British households heat their homes to 22-23C (72-73F). That's hotter than a sunny day on the Med. One in 10 homes (2.5million) is heated to 25C - the same temperature as an average day in the Canary Islands.

This underlines a trend in over-heating homes, with an average rise of one degree every decade in the temperature of the nation's living rooms, from 16C in the 1960s to 20.5C today.
he EST calculates that by switching to modern condensing boiler systems with proper thermostats set at 21C, we could prevent the release of 2.8million tonnes of CO\u2082 per year and the average household could save between £110 and £190 on its annual heating bills.

A condensing boiler works by capturing waste heat that normally escapes into the atmosphere via the flue. Condensing boilers cost between £800 and £1,500. That is £150-£200 more than a conventional boiler of equivalent make and output, so a condensing boiler will pay for itself within a year or so.
