How do you choose between a gas, oil and LPG condensing boiler?

Condensing boilers can be fuelled by gas, oil or LPG. If you can get a gas boiler installed, this is ideal, as gas is the cheapest fuel. If you cannot or do not want to be connected to the gas network, you can opt for an LPG or oil system instead.

FAQs

How often should I get my condensing boiler serviced?
It's important to have any gas or oil fired appliance like a condensing boiler serviced once a year. The flue will need checking to make sure it is clear, and a qualified installer should check that your boiler is running safely and efficiently for you. It's best to check with your manufacturer about service schedules, as some boilers may need servicing more than others.
How easy is it to install a condensing boiler?
Boilers vary in size and shape but most are designed for simplicity of installation. With space being such a premium many boilers are small enough to be fitted by one person into a kitchen cupboard, easily and with minimum disruption.
How can a condensing boiler save me money on my energy bills?
Condensing boilers are more efficient than standard boilers and therefore utilise less gas during operation. Modern conventional boilers can only offer a typical efficiency rate of 78%, whereas the rate for condensing boilers is around 88% - i.e. for every £1 spent spent on gas, 88p is converted to actual heat. This adds up to significant savings on annual gas bills, which will enable you to quickly recoup the initial outlay for the boiler and benefit from the extra savings.

How reliable are condensing boilers?
Condensing boilers are reliable if well maintained and serviced regularly. A Which? survey in 2011 found that 46% of owners who bought a boiler after April 2005 have experienced some kind of fault. Not all of these faults required a repair. In fact the most frequent problem, a blocked drainage pipe, experienced by 11% of owners, is actually a problem caused by poor installation.
