You may detect that one of your radiators is warm at the top and sides but cold in the middle (take care when touching the radiator to ensure that you do not burn your hand). If this is the case you may have a build up of “sludge” in the radiator. Most central heating systems develop this sludge over time. It starts as in the diagram below with a small amount of deposit building up in the bottom of the radiator. As the water flows past... 

As part of its measures to combat global warming the government has introduced a number of new building regulations focused on energy efficiency. From 6th April 2006 engineers/contractors will not be allowed to change/install cylinders or central heating boilers in England or Wales unless they have obtained a qualification in Energy Efficiency. An overview of the impact of these regulations on your home and any proposed heating work is that: – New... 

Leaving no smell and having no taste Carbon Monoxide is very dangerous and toxic. Conventional gas fire or boiler operation produces harmless gases but lack of oxygen can result in Carbon Monoxide production. The standard flue gases from a boiler, or other gas appliance such as a gas fire, contain Carbon Dioxide, this is displaced by Carbon Monoxide when the oxygen levels are reduced. Following the adoption of regular boiler servicing and regulations... 

Carbon Monoxide Detectors play a very important role in keeping you safe in the rare eventuality that a gas burning appliance malfunctions (or has not been regularly serviced) and produces deadly Carbon Monoxide Gas. When Installing a Detector it is important to ensure that it is positioned in accordance with the Manufacturer’s instructions in order to protect you. A carbon monoxide detector will have a limited lifespan as dictated by the battery... 

Most combination boilers and many standard boilers are now installed as Pressurised Systems. This differs from the previous conventional boiler systems which were reliant on a water tank (often in the loft) with a ball float device to maintain water levels within the system. As the self filling water tank is omitted a pressurised system requires filling manually via a filling device, ( a ‘filling loop’). This allows a specific amount of... 

Sometimes there are problems with a central heating system that you can diagnose yourself. If the top of your radiator is cold and the bottom is warm it probably means that the radiator needs bleeding. If you want to check this take care to not burn your hand on the radiator. If the radiator is almost full of air, no difference in temperature between the top and bottom of the radiator will be felt, but in these extreme cases, the whole radiator will...
