Insight Energy Systems offer yearly boiler servicing as well as installation of new A Rated Gas Boilers to homeowners across Devon & Cornwall. We also carry out repairs on existing boilers to help improve efficiency within your heating system.
Has your gas boiler become unreliable? Is it approaching the end of its lifespan? It may be time to consider a replacement.
If you find yourself spending significant amounts on repairs for an ageing boiler that continues to break down, it is often more economical to replace it with a new, energy-efficient system.
A new boiler provides improved efficiency with A-rated energy standards, along with advanced controls and weather compensation for optimal operation.
There are now updated regulations regarding new boilers and heating systems, introduced in June 2022. These fall under Part L of the Building Regulations and aim to improve energy performance in both new and existing properties.
For properties installing a completely new heating system, regulations require systems to operate at a maximum of 55°C. However, in many cases, it may be more beneficial to consider a renewable heating system as a long-term solution.
That said, heat pumps are not always suitable due to factors such as limited outdoor space or site restrictions.
For existing homes where only the boiler is being replaced (without changing radiators or pipework), regulations require that:
Each room has a thermostatic radiator valve
A system filter is installed
The boiler includes load compensation
A suitable chemical inhibitor is added

Modern boilers can achieve 90% efficiency or higher, but in practice this is not always achieved. Issues such as oversizing or outdated controls can reduce performance and efficiency. That’s why a proper Boiler Service in Hessonford and correct system design are essential.
If you receive a boiler replacement quote that includes a make and model but does not include a full heat loss calculation, it is likely to be incorrect and may not suit your property.
A professional Boiler Service in Hessonford can improve system performance, reduce energy consumption, and extend the lifespan of your heating system. The cheapest option is rarely the best — investing in the right system design and servicing ensures long-term savings and efficiency.
