Upgraded cast iron boiler from Hamworthy

Hamworthy, Purewell Variheat mk2. low NOx

The upgraded Purewell Variheat mk2 from Hamworthy features the advanced Siemens LMS controls platform, already used in all of the popular condensing, pre-mix Hamworthy boilers.

It allows easy cascade options, controlling multiple boilers and hot water at the same time, providing energy-saving benefits and allowing flexible control regimes for an extended product lifespan.

The new version is now also equipped with full spark ignition.

The core of the Purewell Variheat mk2 remains the same: a proven cast iron heat exchanger with large waterways especially tolerant of older heating systems. A 6-bar pressure rating makes the boiler suitable for high rise buildings.

The secondary heat exchanger with copper tube and aluminium fins allows the boiler to condense which means it is not only highly efficient but also compliant with all Building Regulations and the Energy related Products Directive (ErP).

Plus, thanks to the low NOx performance (<40mg/kWh, European Class 6), the Purewell Variheat mk2 also scores well on assessments for futureproofed heating system design and overall efficient and effective building performance.

An electrical socket on the front of the new version aids servicing without power outlets in the plant room, along with front cover hooks for quick and easy removal of the cover. A split mains and low voltage wiring harness reduces potential inaccurate fault codes.
