Medium Combustion Plant Directive in commercial heating
The Medium Combustion Plant Directive came into force in 2018 and regulates sulphur oxide and nitrogen oxide emissisions as well as dust into the air from combustion plants. In this article, we look at the MCPD specifically in reference to commercial boiler plants.
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.
Efficient heating system design with built-in boiler controls
An often overlooked aspect of energy efficiency is correct monitoring of external factors which influence the temperature in a building, understanding the usage of premises and how to set up boiler controls correctly. We look how these can assist to set up an efficient heating system.
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.
Driving condensing boiler efficiency
In 2015, we saw the introduction of the Energy-related Products Directive. What is the aim of this legislation and what impact does it have on the commercial heating and hot water market?
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.
Corrosion protection for water tanks water heaters
Protecting your water heater is essential to ensure a continous hot water supply without breakdown. What are the available means to protect water heaters from corrosion? We've compiled information for you in this article.
What is a calorifier?
Ever wondered what exactly a calorifier is? We explain how a calorifier works and what it's used for in heating and hot water systems.
