Reasons to replace your current boiler When should you replace your gas boiler?

Have you started to notice that your heating system is not operating at its optimal efficiency? Perhaps it cuts out from time to time and makes strange noises or when you’re in the shower the temperature fluctuates.

An aging heating system can become less efficient over time and costs you more to maintain meaning there comes a time when it makes sense to replace your old system.

Advantages of replacing your current heating system Reasons for a replacement

There are multiple benefits of replacing your current heating system with either a new Vaillant boiler or heat pump:

  • Keep your energy costs down

    A new energy-efficient heating system makes your property more attractive if you're looking to sell or rent it.

Helping you make a sustainable choice

Heat pumps – an energy efficient heating solution

Utilising the heat from the environment, heat pumps are one of the most energy efficient heating options. There are different kinds of heat pump that draw the natural heat from the air, ground, or a water source.

Heat pumps use a refrigerant (R290) to absorb the heat. This is compressed to further increase the temperature, which can then be used to heat your home.

Air source heat pumps are suitable for a wide range of properties, but to help them operate at maximum efficiency, it's important your home is well insulated with double or triple glazed windows and loft insulation.
