Commercial heating and hot water knowledge articles

Think the Energy-related Products Directive saw the end of cast iron boilers? Our cast iron boilers changed this, they can not only condense but are also ErP compliant. Find out how we've achieved this.

​The UK Government has a net zero goal in place for 2050, which requires greenhouse gas emissions to be reduced to as close to zero as possible, with any remaining being balanced out by removing an equivalent amount.

Find out how a calorifier, or indirect fired hot water cylinder, works as part of an indirect fired hot water system.

The energy efficiency of air source heat pumps is not in doubt; they are up to three times as efficient as a gas boiler. But to maximise the energy efficiency of a commercial heat pump solution, there are four key aspects that need careful consideration: building fabric, building services, heat pump system design, and usage.

Understand how to size a low loss header to maximise efficiency in residential and commercial heating systems

When it comes to refurbishments, it is important to protect new equipment. This can be done by hydraulically separating the primary and secondary circuit. We look at different methods to achieve this.

Part of the BESA conference 2021, Hamworthy discusses the challenges and benefits of Hydrogen plus questions from the audience.

Hydrogen gas as a low carbon fuel source is currently a hot topic that will continue to be so for the coming decade. We take a look at what Hydrogen is, how it’s produced, and when it may be used to heat our homes and buildings in the future.

What is an indirect water cylinder or tank? Exploring calorifiers and indirect fired hot water cylinders and tanks, their features and benefits.

When purchasing new equipment, there is always the question concerning upfront costs and running costs. In this article, we compare both of them and explain the advantages of looking at the long-term costs of heating equipment.
