Central heating is a complicated system and there are many individual parts and aspects that may go wrong. We are fully trained, gas certified. With 30 years of experience in installing and repairing full central heating systems including combination (combi) boilers and conventional systems. If you are looking to have a new installation then please give us a call for a no obligation quote and to discuss your requirements. We have provided an overview below of the main types of heating systems.
Most Combi’s run on mains pressure water, thus do not require tanks to be placed in the loft. They also eliminate the need for a hot water cylinder as they instantly heat the water when it is needed. Another benefit with the combi is that, due to it running from the mains water supply, you can create an effective power shower without the need for a pump.
These require two water tanks located high up (usually in the loft) the first, a Cold Water Storage Tank the other an Expansion/Feed tank, these also require a Hot Water Cylinder (usually situated in an "airing cupboard"). The storage cylinder holds a large quantity of hot water that is available immediately (or as soon as the feed allows). When this store has been used up however it has to be reheated which can take up to 1 hour.
Here at D&J Plumbing and Heating we are experienced in all aspects of domestic and commercial plumbing work. From full bathroom and kitchen refits to the rerouting of plumbing to accomodate home extensions etc.
