### How Much Gas Does a Boiler Use Per Hour? | Viessma

How much gas your boiler consumes will depend on its size, efficiency and how many hours it’s in use per day. Boiler sizes are measured in kilowatts (kW) and range from 24-27 kW, 28-34 kW and 35-42 kW. A house with one bathroom and 10 radiators would need a 24-27 kW boiler, whereas a large house with over 20 radiators and three bathrooms or more would need a 35-42 kW boiler.
