Gas Boilers: The Information You Need - Central heating UK
The running cost of gas boilers is approximately £607.50 per year, which is much lower than the £2,160 cost for a fully electric central heating system. The gas price is still lower than if the Economy 7 tariff is applied. Electric heating costs fall to £1,215, calculated from the lower 9p/kWh for off-peak hours.

Most Economic Boiler Temperature? | Screwfix Community Forum
Oct 17, 2014 · If the system were to have a thermostat with weather compensation fitted, this works by reducing the flow temperature of the boiler so matching the output of the radiators, proportionately, to the temperature difference between inside and outside. Most systems are designed around a difference of about 22*C, i.e. -1*C outside temperature.

10 Things to Know About Boilers | Boiler Expert Minneapolis
Today’s boilers are water heaters and typically use natural gas. Most can heat water in a range from 145-190 degrees, depending on the radiation system. 2. How do boilers provide heat? Boilers provide radiant heat, which warms objects in a room. In contrast, a forced air furnace warms the air in a room, which means objects absorb heat more slowly.
