WHAT IS AN UNVENTED CYLINDER?
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.

Arrived exactly at stated date and time, completed job within quoted timetable at the quoted price, absolutely hassle free and would fully recommend this company to anybody, have also provided excellent back up service as my wife and I are elderly and not the quickest these days in picking up new and totally different technology to the old boiler system. Well done Paul and his employee Ray & Wendy Savage Holmfirth West YorkshireVerified reviewerJob location: HD9

I needed a replacement boiler and contacted PDL since they had been recommended by a family member. Paul was very knowledgeable and explained the various options when he came to provide the estimate, which he sent through on the same afternoon. They (Paul and Robert) have done a thoroughly professional job of installing the new boiler (and shower!). They worked constantly throughout the two days that it took. I was kept informed as to progress throughout. They took care to minimise the amount of disruption and protected the carpets etc. from damage. After installation, Paul explained clearly how to operate the system and to use the Vaillant vSMART app. I am very pleased with the result and would not hesitate to recommend PDL. read less
