Hot water cylinder thermostat
Priority for Completion: Medium
This recommendation is triggered if the property has a hot water tank without a thermostat. The exact benefit will depend upon a wide range of factors including the age and model of the boiler, the cost of the fuel used and the amount of hot water used in the home. Generally, the less hot water is used and the older the boiler, the bigger the savings will be. However, changes to your home's heating system should be undertaken by professional installer and may require some financial investment so we have rated this as being medium priority. This work may also have to be undertaken as part of other changes if required by the current Building Regulations.
What does a hot water cylinder thermostat do?
If you have a tank for your hot water you will need to heat up the water it contains to have hot water to use in your home. Usually this is achieved by setting a time control to heat it up at certain times of day.
A hot water cylinder thermostat measures the temperature of the water in the cylinder and only heats it if it is too cold. When the water reaches the required temperature (usually set to between 65 and 70 °C) it stops it being heated any hotter. This save you energy and money as less heat is wasted.
Fitting a hot water cylinder thermostat
It is generally not difficult to install a hot water cylinder thermostat but, for safety, it will require a suitable professional.
Building Regulations now require that alterations to heating systems are subject to Building Control. The easiest way to comply is to make sure all work is carried out by a suitably qualified professional who is registered with an appropriate industry scheme. It can be very dangerous to attempt this work if you are not fully competent and, if you are unable to prove the work was completed properly, it could affect your ability to sell your home in future.
