This is an interesting and particularly practical topic, because every kilowatt-hour counts when it comes to energy prices. A gas boiler’s consumption isn’t a fixed number, but if we consider a common condensing boiler in a family home, we can make fairly accurate estimates.<\/p>\n\n\n\n
Here’s a simple overview of how to find out:<\/p>\n\n\n\n
How much gas does a boiler actually “consume”?<\/p>\n\n\n\n
Consumption depends mainly on the boiler’s power (usually 12 to 24 kW) and the power it’s operating at. A boiler rarely operates at 100%.<\/p>\n\n\n\n
Operating Modes: Approximate gas consumption per hour
Maximum power (e.g., water heating) 2.0\u20132.5 m\u00b3
Normal temperature maintenance 0.5\u20131.0 m\u00b3
Low power (high-efficiency mode) 0.2\u20130.4 m\u00b3
Tips for reducing gas bills
If you want to save money without freezing indoors in your (recently repaired) sweater, try these steps:<\/p>\n\n\n\n
Reduce the water temperature to the radiators: with condensing boilers, the lower the return water temperature, the greater the efficiency. Try setting the heating water temperature to 45\u201355\u00b0C.
The thermostat is your boss: reducing the temperature by just 1\u00b0C can save you up to 6% on heating costs.<\/p>\n\n\n\n
Remove obstacles: curtains in front of the radiator or laundry hanging directly above it are the enemies of savings. Heat should spread throughout the room, not onto wet socks. Maintenance inspection: a clogged exchanger can increase consumption by 10-15%. A clean boiler is an energy-efficient boiler.
Beware the myth: turning off the heating completely when you leave for work is often not worth it. The walls cool down, and the boiler must then consume a huge amount of energy to reheat them. It’s better to lower the temperature by 3-4 degrees.<\/p>\n\n\n\n
A quick calculation for your wallet
If we consider that 1 m\u00b3 of natural gas has an energy value of approximately 10.5 kWh, you can easily calculate how much an hour of intensive heating will cost you based on the current price per kWh on your bill.<\/p>\n\n\n\n
