What causes hot water to stop working?

We don’t realise how reliant we are on hot water until it stops working. It impacts our cooking, cleaning and hygiene, especially during periods of low temperature where we spend more time indoors. Understanding what can cause a loss of hot water is essential to helping the problem get resolved quickly, with the right part able to be sourced and fitted as needed. In this blog, you’ll find the most common factors that lead to hot water not working in your home.   "

Why is my central heating working but the hot water isn’t?   

Many modern boiler systems are combi boilers that can provide both hot water and central heating. This leads many people to believe that an issue with their boiler will affect heating for both equally. However, combi boilers heat and divert hot water as it is needed for the purposes of both central heating and hot water outlets. This means it is connected to both radiators and taps in the property. There can therefore be issues which are isolated to either of these.  Combi boilers use condensing technology that allows for more efficient heating by harnessing latent heat that resides in flue gases. This is a natural by-product of gas burner heating, which is then ‘recycled’ to decrease the amount of fuel used by the boiler. This is important for these systems as they function as a hot water boiler and a central heating boiler.
