So it’s time to replace your boiler, this is a big deal, ordinarily a sizable investment, so it’s crucial to make the correct choice from the off. We’ve decided to add this information to help guide you through the process and provide you with an insight into exactly what you need to know.
- Quotes – identify at least 2 heating companies ideally 3 to provide you with quotes.
- Type of boiler – know the type of boiler you want/ need 3 main types (domestic).
- Heat only boiler -This model is straightforward, it’s a boiler in its most basic design and probably the most common boiler used in the UK. It just contains everything required to heat water which will travel around the cylinder and radiators. It requires an external pump to work. Heat only boilers are the only kind that can work on an open vented system, what I mean by that – it can be fed via the small ‘feed and expansion tank’ in the loft space.
- System boiler – This type is very similar to the heat only version, the main difference is, these are designed to be fitted on a pressurised ‘sealed system’ and they are equipt for that purpose. Inside it has an expansion vessel (I won’t go into detail about that now) additional safety devices plus it also contains its own circulation pump. These kind of boilers are perfect when it comes to a like-for-like system boiler replacement or if you’re replacing a heat only boiler and would like to remove the small feed and expansion tank in the loft.
- Combination boiler – Combi’s are becoming increasingly popular, they have a few benefits that can’t be overlooked. A combi boiler essentially replaces everything on a standard heating system – they are fully pressurised, so there is no need for any tanks in the loft, a totally dry loft can be quite reassuring for some people. Your hot water becomes main pressure – a massive plus, a lot of people in the UK have issues with upstairs tap/ showers not providing enough pressure as they’re tank fed, installing a combi would resolve this issue. Another big positive with a combi boiler is that your airing cupboard is totally stripped away – the hot water cylinder is removed as it is no longer required, freeing up some valuable cupboard space.
