Boiler Types Explained
The gas boiler is the most important part of a central heating system. It's like a big fire that has a continuous supply of gas streaming into it from a pipe that goes out to a gas main in the street. When you want to heat your home, you switch on the boiler with an electric switch. A valve opens, gas enters a sealed combustion chamber in the boiler through lots of small jets, and an electric ignition system sets them alight. The gas jets play onto a heat exchanger connected to a pipe carrying cold water. The heat exchanger takes the heat energy from the gas jets and heats the water to something like 60°C (140°F).

Oil boilers are now capable of doing practically everything that their gas counterparts can do and if you live in a area with no access to mains gas, oil-fired central heating is often the right choice for you. One of the major benefits of using an oil-fired system is that you can shop around for your fuel supply at any time as you are not tied into lengthy energy contracts.
While oil boilers are less common in the UK than gas boilers, there are still a large number of oil-fired systems and we are able to perform practically all of the same services on oil systems as we can provide for gas systems including installations in many areas.
What is LPG? Liquid Petroleum Gas (LPG) is a mixture of butane and propane stored under moderate pressure. Its use is on the rise in the UK especially in areas where there is no access to mains gas. LPG takes far less space to store than oil and so many customers who have previously used oil-fired systems have made the switch to LPG.
LPG boilers are also more environmentally friendly than oil systems as they burn clean. They are also better at preventing leaks or theft.
Electric heating is a new and innovative option which is becoming more popular in the UK. For homes with no access to mains gas, electricity has become a viable option. In addition, electric boilers do not require any flues or exhaust vents which means that they can be installed without disturbing the walls or roofs of the building. This can be very important when trying to heat listed buildings or flats in blocks which would traditionally require expensive scaffolding to provide access.
Indoor air quality is another area where electric systems can be beneficial as they do not produce any moisture or particulates. However, electricity is usually more expensive than gas per KW and so heating bills can be more expensive when using an electric boiler
