Are There Any Downsides To A Combi Gas Boiler?
Combination boilers provide both instant hot water and central heating, but not at the same time. They have a ‘hot water priority’, which means that when hot water is being run there is no heat output to the radiators. They also struggle when a demand for hot water is made from more than one outlet at the same time – such as a shower and a sink tap – because the hot water flow rate is divided by each water source used at the same time. Also, you cannot boost the water pressure to a shower by adding a shower pump when a gas combi boiler is installed. However, if there isn’t a great demand for hot water in your home then combination boilers are ideal, particularly as they do not take up a lot of space. They are also very easy to install and cheap to run. However, they can be expensive to repair and many are designed to be replaced after five years.
