The benefits of stainless steel in hot water generation
With stainless steel becoming a popular choice for hot water products, we take a look at some of the key factors driving this trend.
NOx emissions from commercial boilers
NOx emissions are the 'hot topic' of the industry. In this article, we investigate why they are a reason for concern, how they are generated and what we can do to reduce them.
Cleaner Heat Cashback
The Government has introduced a commercial boiler scrappage scheme for London to cut carbon and NOx emissions in the capital to improve air quality and energy efficiency in non-domestic buildings. We take a look at the criteria for a replacement, how the application works and how you can become a Hamworthy-approved installer.
ErP Energy Labelling
Energy labels indicating energy efficiency were introduced in 2015 to be applied to consumer products. A part of our product range is also affected.
ErP Directive for water heaters
The ErP Directive does not only affect boilers but also water heaters. The requirements are not limited to energy efficiency and noise levels. Read our article to find out more.
ErP-compliant boilers
The Energy-related Products Directive was one of the major legislations which has almost eradicated atmospheric boilers from the market. Learn more about the directive and its requirements here.
Energy legislation
Over the last few years, the government has introduced legislation to achieve carbon savings targets. Do you know which legislation exists? Have a look at this page to learn about it and what's behind the acronyms.
Load matching in multiple boiler installations
The use of several small boilers compared to one big boiler can make your heating system a lot more efficient. How it works - learn more about the benefits of large turndown ratios and improved system efficiencies.
Energy Technology List
You can benefit from tax deductions if you decide to invest in energy saving heating equipment. The Energy Technology List tells you which products are eligible. Learn more about it and which products are eligible for Enhanced Capital Allowances.
ErP-compliant cast iron boiler
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.
