Installation of Heating Controls

If your heating controls are old - over 12 years, says the Energy Saving Trust - then you could benefit from replacing them. The older room thermostats are particularly inaccurate.

The energy and cost benefits from improved controls can be achieved straight away with any boiler. In fact, the percentage improvement from controls added to an older, less efficient boiler will result in a greater total energy saving than with a modern boiler.

Get home energy savings!

You don’t have to wait until you get a new boiler to upgrade or install heating controls. However, there are no minimum standards for existing systems. Adding or improving controls could help you to stop wasting energy and as a result, save money on heating bills.

Competent Person Scheme installers can self-certify their work as compliant with Building Regulations. They can also notify the local authority on your behalf and issue you with a certificate on completion which can be used as proof of compliance. It will also show up on a solicitor’s Local Authority search when you sell your home. (Energy Saving Trust)

The heating will not work if the room thermostat has switched the heating off. And, if you have a hot-water cylinder, the water heating will not work if the cylinder thermostat detects that the hot water has reached the correct temperature.

The best way to do this is to set the room thermostat to a low temperature – say 18°C – and then turn it up by one degree each day until you are comfortable with the temperature. You won’t have to adjust the thermostat further. Any adjustment above this setting will waste energy and cost you more money.

Costs and maintenance

Costs will vary depending on what type you go for. Ask your installer for a breakdown of the costs of each part if necessary.

If you are over 70 years old, or on certain benefits, you may be entitled to receive discounted or free controls and replacement heating system though Warm Front, Warm Homes or other regional schemes.

Hours to install

The installation time will vary with the products and the complexity of the controls systems but a the time to fit simple heating controls will be hours with a competent installer.

A competent installer will also be able to assist you to choose the most appropriate controls for your home and situation.

What is the difference between timers and programmers?
A timer switches your heating system on and off at the same times every day, whereas a programmer allows you to program in different heating times for different days of the week to suit your lifestyle.
How can I use my thermostat best to save energy?
If energy efficiency is important, keep in mind that wide temperature fluctuations in thermostats can waste energy, increasing the cost of running your heaters and decreasing your comfort level.
What is a programmable thermostat ?
A programmable thermostat is a time clock and thermostat in one. Programmable thermostats simplify the use of a heating system and should be considered as an upgrade from the standard manual dial thermostat and time clock arrangement still installed by most new house builders.
