Frequently Asked Questions
FAQs
Is a higher kW boiler better? ›
Boiler size is measured in kilowatts (kW). A kilowatt is a unit that defines how much energy your boiler outputs in the form of heat. As a general rule, the more heat and hot water you require for your home, the higher the kW boiler you will need.
What kW boiler should I get? ›For an average three or four-bedroom house that typically has around ten radiators a small or medium boiler (for example 24-30 kW) should be sufficient. A larger house with substantially more radiators or an en-suite bathroom will generally need a larger one, typically 30-35 kW.
How many kW do I need to heat my house? ›The first and the easiest method to calculate your home's heating capacity is laid down in the 'building code' basics: one kilowatt of heat will be required for heating every 10 square metres of your home. Hence, for heating a 100 square meters home, one will need to look for a 10 kWh boiler type.
What size boiler do I need for a 1200 sq ft house? ›Boiler Capacity
An easy rule-of-thumb for BTU requirements is to figure that you need about 50 BTU per square foot of interior space in a cold climate; 35 BTU per square foot in a moderate climate; and 20 BTU per square foot in a hot climate.
As a rough guide most apartments and smaller houses, with up to 10 radiators will require a 24-25kw boiler. A 28-30kw would be installed for a medium to large 3-4 bed house with up to 15 radiators, and a 33-35kw and a 40kw would be for a large house with anything up to 20 radiators.
What does 30 kW on a boiler mean? ›For combi boilers, the kW rating equates primarily to more hot water so, the bigger the number, the more hot water the boiler is able to deliver. A 30kW combi boiler output is considered 'middle of the range' and is very popular with many homeowners.
How many radiators will a 32 kW boiler run? ›A 32kW conventional boiler will best suit a home with 15 to 20 radiators and 2 to 3 bathrooms. Below you will find 32kW boilers that you can compare to see which will meet your heating and water demands best.
Does a higher kW boiler use more gas? ›It's true that a 36kW boiler will cost more to run than a 24kW model – after all, you pay for each kW you use. A 36kW machine will use 12kW more per hour than a 24kW one, so you'll pay 50% more.
How many kW boiler for a 4 bedroom house? ›What boiler is suited for your 4-bedroom-house? As the average 4 bedroom house has between 10 and 15 radiators, you will most likely require a boiler with an output rating of around 20 to 30 kW.

|---|---|---|
| 1,200 sq ft | 11 – 13 kW | 13 – 15 kW |
| 1,500 sq ft | 14 – 16 kW | 16 – 18 kW |
| 1,600 sq ft | 15 – 17 kW | 17 – 19 kW |

How much does a 30kW boiler use? ›Your boiler size (in kW) x the number of hours used per day = daily gas consumption (measured in kWh). For example, if your boiler has a size (in power output) of 30 kW and you use it for 5 hours each day, you will be using 150 kWh of gas each day.
Is 30kW boiler enough for 2 bathrooms? ›You need to measure it against the size of your house and number of bathrooms. A small flat or house with one bathroom can run perfectly well with a 24-27kW combi boiler. A large house with 3 or more bathrooms will suit a system boiler with an unvented cylinder.

How much does it cost to run a 30kw boiler per hour? ›The calculation is the kWh of your boiler multiplied by the price of 1kWh of gas, then divided by 100. For example – if your boiler used 30kWh of gas per hour, and your gas cost 10.2p, it would be 30 x 10.3 = 309p, divided by 100 = £3.09 per hour to run your boiler.
What size electric boiler do I need for my house? ›As a basic rule, you should add 1.5 kW for every radiator in your home. For example, if you have six radiators, you should get a 9 kW electric boiler. This rule may vary depending on how high your ceilings are, whether you have single or double glazing and how effective your insulation is.
Which boiler is more energy efficient? ›A condensing boiler recovers more heat from the exhaust flue gas and uses it to heat the central heating water, making it more efficient than older boilers.
