We can repair, replace or inspect your Thermostat on the spot!

Thermostats are essential in maintaining good boiler health, be it gas or oil that you are using. They prevent overheating of your cylinder by ensuring that your boiler switches off when the water has reached the desired temperature thus saving you money and energy too. Thermostats also help to prevent over-boiling of the water heating system which if not maintained properly, can lead to problems and ultimately damage to your central heating system further down the line. If you suspect that your thermostat is broken or not working as efficiently as you think it should be, then call one of our qualified electricians at our Dublin office and we will be happy to come out and inspect the problem for you.
