What is the best option to replace my solid fuel/ oil boiler?

Trianco has a long history of manufacturing Oil and Solid Fuel boilers. However with a push to reduce carbon emissions, we no longer manufacture either. But, as we continue to sell spare parts and with many homes around the UK who still have a TRO or TRG boiler we receive many customer enquiries. Recently, a number of our customers have contacted us raising concerns about what options are available to them if they wish to replace their oil or solid fuel boiler. This includes people who don’t have access to natural Gas and are therefore “off-gas”. 

If you’re still relying on a solid fuel or oil boiler, upgrading your heating system is one of the smartest decisions you can make for your home—both financially and environmentally.

But what’s the best replacement?

Let’s break it down simply - for most homeowners, a heat pump is now the top choice for replacing oil or solid fuel systems.

Why?

  • Highly efficient – produces up to 3–4x more heat than the electricity it uses
  • Lower running costs – typically cheaper to run than oil in the right home
  • Greener heating – no fossil fuels, significantly reduced carbon emissions
  • Future-proof – supported by UK grants like the Boiler Upgrade Scheme

In a well-prepared home, a heat pump offers the best long-term value

Air Source Heat Pumps

An air source heat pump is an electronically powered device that absorbs air which passes through tubes containing refrigerant fluid to produce heat. Heat pumps are known for their high efficiency and are normally three times more efficient than gas boilers. Trianco Activair High Temperature Air Source heat pumps have been developed with cutting-edge technology. Including the R290 low global warming refrigerant, our Activair has an efficiency energy label of A++ for both heating and hot water. Find out more about our Heat Pumps here

Many people are also not aware that they may be eligible for Government Grants to have their off-gas heating system replaced
