Renewable Energy Services
Solar powered water heating is the most popular form of solar energy used in the UK. The solar panels provide heat to the hot water system via a twin coil hot water cylinder, which is supplemented by a boiler. A typical solar heating system, if correctly sized, should provide around 50-70% of the domestic hot water requirements.
Solar Thermal Heating
Solar thermal panels rely on solar radiation not direct sunlight to heat water. Contrary to popular belief, the amount of solar radiation received in most of the UK is sufficient for solar water heating to be a viable supplement to existing domestic water heating. The radiation in the UK is made up of direct radiation on sunny days, which accounts for around 40%, and diffused radiation on cloudy days, accounting for 60% of the total.
Thermostatic radiator valves (TRV’s)
Using thermostatic radiator valves is a cheap and energy efficient way to control the temperature to individual rooms and if turned down when not needed can also help reduce heating costs. A lounge or dining room will normally have a higher temperature setting than a bedroom.
Energy efficient heating
There are a number of energy efficient controls that can be fitted to your existing heating system, which will help save you money and give more comfortable heating temperatures.
Electronic room thermostats and programmable room thermostats
Modern, electronic room thermostats and programmable room thermostats are more accurate, usually + - 0.5°C, at controlling a set temperature than the older, mechanical thermostats. This gives a more consistent and therefore more comfortable room temperature.
A programmable room thermostat allows you to choose different temperatures at different times of the day and night. It also allows you to set different temperature profiles for each day of the week.
A programmable room thermostat does not switch your central heating off in the same way as a normal programmer. Instead, the boiler is always ready to provide heat if the air temperature falls below the current thermostat set temperature. It controls your heating system efficiently, providing comfortable temperatures at the least cost.
Hot water cylinder thermostats
Many homes do not have a thermostat fitted to the hot water cylinder. Not only is this inefficient but can also be dangerous as there is no control on the hot water temperature.
Magnetite (black sludge) has been a problem in heating systems for many years. It will cause costly damage to central heating systems and modern boilers. One solution is to fit a magnetic (and non magnetic) filter on the return pipe to the boiler. This not only protects the boiler, it helps keep the heating system clean and makes it cheaper to run.
