How Would a New Heating System Benefit You?

Central heating installation By fitting a new high efficiency condensing boiler and improving your heating controls, you could cut your home’s carbon dioxide emmisions and significantly reduce your heating bill. Our Gas Safe registered central heating engineers are fully trained and qualified to design, install, repair and service you central heating systems.

High efficiency condensing boilers are the most efficient boilers available. They recover as much of the waste heat which would escape from the flue of a conventional boiler. The best high efficiency boilers convert more that 90% of their fuel into heat; conventional boilers just 78%.

Types of Central Heating Systems

The most common types of central heating systems and boilers are as follow:

Combination – instantaneous hot water and pressurized heating system

Conventional – stored hot (copper cylinder) and cold water, boiler and feed and expansion tank

System – stored hot water, mains fed cold water and system boiler and an Unvented Cylinder.

Each one system have their own advantages and drawbacks and we have unlike many other installers, we have no particular preference for either one. What determines the choice is largely the property type, size and customer requirements.

In general, Combination boilers are suitable for flats and houses where the hot and cold water drawback are restricted to ideally one bathroom / wc and a kitchen (maximum 2 bathrooms). This is because, Combination Boilers are mains fed, and draw offs from multiple locations can cause water supply issues.

Conventional systems tend to be in older properties. These normally comprise of a heat only boiler, a copper cylinder which stores the hot water, a cold water storage tank and a Feed and Expansion tank. They mains water will supply both of these tanks and the kitchen sink cold tap, and usually no more. The advantage of these is that they do not suffer the pressure drops that combination set ups sometimes experience because the water is stored. However, the space required for all the aspects of this system can be quite extensive and also the running costs can be relatively large for only a one person household.

Central Heating

Finally a heating set up that comprises of a System boiler is quite similar to that of a conventional one, but usually the cylinder is an Unvented Cylinder. (for example a Megaflow). Ie there are no cold water storage tanks or Feed and Expansion tanks. The cylinder is mains fed so the pressure at the hot tap will be similar to the mains cold feed entering the property. The advantages of this are the space savings that can be achieved by not having the tanks and greater flow rate at the hot tap. These cylinders can also be stored in garages and in attics. The disadvantage can be the cost of them and also a requirement of 22 litres per minute of mains water flow rate.

Avoiding the Waste of Heat Can Drastically Reduce Heating Bills

A Leicestershire borough is leading the way in heat saving tactics by rolling out state of the art vehicles across the town of Melton that pinpoint poorly insulated houses. The HeatSeeker vehicles developed by the Energy Saving Partnership use thermal imaging technology to identify property’s which are lacking sufficient insulation. With the prolonged cold weather [...]

Protect yourself with a new boiler

As the cold winter weather hits the UK, the struggle for household boilers to cope with the weather increases and in some cases, boilers can turn into silent killers. Badly maintained gas central heating boilers or boilers that are blocked or leaky can release carbon monoxide, known as the “silent killer”. Carbon monoxide is known [...]
