Insight Energy Systems offer yearly boiler servicing as well as installation of new A Rated Gas Boilers to domestic customers across Devon & Cornwall. We also carry out repairs on existing boilers to help maintain efficiency within your heating system.
Has your gas boiler become unreliable? Is it over eight years old? It may be time to consider a replacement.
If you find yourself spending hundreds of pounds 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 better performance 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 current energy efficiency 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 installation constraints or proximity to neighbouring properties.
For existing homes where only the boiler is being replaced (without changing radiators or pipework), regulations require that:
Each room has a TRV or room thermostat
A magnetic 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 Issues such as incorrect sizing or outdated controls can reduce performance and efficiency. That’s why a proper Boiler Service in Smithaleigh and correct system design are essential.
If you receive a boiler replacement quote that includes a make and model but does not include a detailed system assessment, it is likely to be incorrect and may not suit your property.
A professional Boiler Service in Smithaleigh 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.
