New Pre-Plumbed unvented cylinders

We have recently added pre-plumbed unvented cylinders to our product range. 
They come in two sizes the iPP 175 (single bathroom + en suite) and 250 litres (twin bathroom + en suite). 
These stainless steel unvented cylinders provide mains pressure hot water. They are fitted with a pre plumbed pre wired S plan arrangement with two heating zones. 

Advance pre plumbed stainless units combine an attractive appearance with superb heat loss characteristics. They are both ERP rated as B. Perhaps the most exciting development is the air gap technology employed which features a patented device to maintain the air bubble in the cylinder.
