Keeping your central heating system clean is essential to its health and longevity. Power flushing is a preferred method because it can be completed quickly and it offers the most effective and thorough way of cleaning all pipes and radiators at the same time.

When it comes to installing a new boiler or upgrading an old one, S.J. Denness Gas Services know how important it is that you understand how the different types that are available operate. This will help you to decide which is the right one for you and your household. These days, there are three main types of water boiler available; conventional, combi and system. Each type has differing features and benefits. Knowing these will ensure that you choose the right one. The most popular choice is a combi boiler.

If you're looking for Gas Safe registered plumbing and heating engineers to install, service or repair your central heating system, then S.J. Denness Gas Services should be your first choice. With outstanding workmanship and superb customer service, you'll know you've chosen correctly. We will agree a time to come to your home and survey each room to ensure that your new central heating system is designed specifically, and correctly, to meet your household's needs. We will then provide a free, written quotation for you to consider.
