How does Hamworthy Heating’s new boiler stack up?

Hamworthy Heating has improved on an icon with its latest range of condensing boilers. The Wessex ModuMax mk3 boiler builds on the heritage of a range that has been in production for 10 years. Features include enhanced built-in control, ∆T of up to 40 K and a 10-year warranty on the primary heat cell.
Thee boilers stack vertically , offer close load matching and sit on a very small footprint. The ability to operate on a temperature difference between flow and return of 40 K helps maximise condensing performance and assists in designing heat networks.
The Wessex ModuMax mk3 is a stainless-steel, high-efficiency, fully modulating condensing, pre-mix floor-standing boiler.
There are five modules with outputs at 80/60°C of 97, 116, 147, 196 and 254 kW. Individual boilers can be stacked up to three high in up to 15 combinations.
The built-in Siemens controls enable control of up to 16 boilers in a master/slave configuration — removing the need for separate controls or building-management systems in smaller applications.
An air-inlet feature keeps combustion air and burner free of dirt particles and speeds up service and maintenance. It is all housed in a new robust steel casing with an easy-to-remove front cover.
Keith Thompson, sales and marketing director, says, ‘Although the look of the boiler has changed, it has retained the benefits of this well-loved boiler range. Plus, we’ve included all the new features at no extra cost to our customers.’
