Modular boilers for heat networks
Modular boilers are a compact and flexible solution. In heat networks, they can provide an excellent back up and top up solution to support other equipment such as CHP. Learn more about why modular boilers are being used in district heating schemes.
Modular boilers load matching in heat networks
How do you design a heat network to efficiently match peak and low heat loads? Find out how to create a high boiler turndown ratio for your modular boiler system
No flow boilers – application and installation
No flow boilers don’t depend on the system circuit flow for safe operation. But how does a no flow boiler work? Understand the application and installation of no flow boilers for cost effective heating system design.
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.
Open vented heating systems compared with sealed systems
Open vented boiler systems have been traditionally used. In modern times, sealed heating systems are the favourite choice. We look at differences between both and how to deal with them when refurbishing your heating system.
Primary circuit or boiler shunt pumps in commercial heating
A question we get asked a lot at our CPD seminars is: ‘Which is best - a boiler shunt pump or primary circulation pump?’ There's no correct method, as long as the minimum flow is always maintained. And it will always depend on the project. In this article, we’ll look at the different pump options and their pros and cons.
Refurb or replace – what to consider when upgrading your commercial heating system
What to consider when you are refurbishing your plant room. Understand your heating and hot water replacement options.
Sizing hot water systems for sports facilities
Sizing hot water systems is a science in itself. Getting it right means you have a sufficient hot water supply without the risk of paying more for hot water you don't need. Find out more in our article.
Specifying hybrid heat pump systems in the transition to low carbon energy
While the installation of heat pumps will play a large part in helping the Government achieve its net zero target – air source heat pumps (ASHPs) can fit almost anywhere: retrofit or new build, domestic or industrial and commercial, mixed-use developments – but what about the opportunity in buildings that are not ready to rely completely on low carbon heating systems?
Stratification in water heaters
Stratification in water heaters can be problematic. We explain what causes it and how it can be avoided to prevent the growth of Legionella bacteria.
