An unvented cylinder is a hot water cylinder that is supplied directly by mains water instead of by a tank in the loft. This makes the performance of the hot water (pressure and flow rate) much better.
You get equal performance of hot and cold water throughout your property. This makes for fantastic shower performance and rapid bath fill.
The unvented cylinder will also cope much better with multiple hot water points than a combi boiler making them suitable for large properties. They are extremely well insulated making them highly efficient. The heat recovery is also much faster than a traditional cylinder.

Excellent work by excellent engineers. We've used them time and time again. Excellent customer service.
PDL came with the personal recommendation of a friend and I was not disappointed. I was very pleased with the expert knowledge and with the quality and efficiency of the work carried out.
No problem with anything. Neighbour also had same heating system/boiler installed as a result of our recommendation.
The installation was to a very high standard. The heating engineer was polite and a tidy worker. I would have no hesitation in recommending PDL to other potential customers.
Outstanding and very clean after the work was complete, would use again without a doubt.
We had a full gas central heating system installed and from start to finish the completion of the work PDL were very professional. We would have no hesitation in recommending them to future clients.
Paul and Debbie were efficient, patient, reliable and knowledgeable. Paul fitted our heating system with the minimum of disruption. We would highly recommend. We are delighted with our new central heating system.
PDLs' work is excellent, all staff arrived as arranged and were polite and courteous at all times. I would (and have) recommended PDL to several other people. On a recent visit by a local Estate Agent, he remarked that the Central Heating was one of the best installations he has seen in a long time!
1st class in everyway from the first phone call which was friendly and gave all the information I needed. Work was excellant, and they look after your house as if it was their own. Marks out of 10, well all I can say is 10 is not enough. If you want the best use PDL.
