Keston | Heat 2 Range

Keston Heat 2 55kW Heat Only LPG Boiler – 355126

The Keston Heat 2 55kW Heat Only LPG Boiler (355126) is a wall-mounted regular boiler designed for demanding domestic and commercial heating installations. Using LPG fuel, this high-output boiler is suited to projects requiring a heat-only heating solution, with flexible flue options that can help address challenging installation layouts.

A key feature of the Keston Heat 2 is its twin-flue capability of up to 18 metres, offering greater installation flexibility than conventional arrangements that rely on a concentric flue through an external wall. The boiler also features an integrated low-energy modulating pump, a 5:1 turndown ratio and a serviceable flue non-return valve.

With an ErP A rating, Class 6 low-NOx classification and compatibility with commercial control systems, the Keston Heat 2 55kW LPG boiler is designed to support efficient heating system design. Its compact installation footprint and removable panels on three sides also help make servicing and maintenance more accessible.

Supply of 40 x 8kg Harveys Block salt

Excellent service and despite slight delay on delivery date kept us informed of revised date

Pretty good but delivery was delayed by a week with no communication

Pretty good but delivery was delayed by a week with no communication. If we had been told there was a delay then I would have been happier.

Lockshield valve key.

This lockshield key is perfect for the use with the 28mm lockshield valve which I ordered.

Primaflow or not?

I think that this item may not have been the Primaflow branded valve since there was no branding on its plastic bag or the valve itself. On the website a non-branded valve was listed at a more expensive price, which didn't make sense, and I suspect that this may be the one that I received. However, it was perfectly functional, although the bore was small.

Quality valves at an excellent price.

I am very pleased with the two 28 mm Primaflow QLC Lever Ball Valves which were received in perfect condition within 48 hours of being ordered. These are quality items at a good price. However, I would really have liked to have been told that they would be delivered by Royal Mail, and also they were poorly packaged although thankfully did not suffer as a result.
