Featuring large heat exchangers in which, due to their low water content and larger surface area, hot water performance is vastly increased. With a low system pressure cut off switch, the combi protects itself in the unlikely event of system water loss.
Additionally, there are two very accurate electronic temperature controls which allow the boiler to operate in condensing mode on central heating, whilst maintaining its instant hot water production. Benefits include 24 litre expansion vessel, neon diagnostic indicators and a factory fitted internal condensate trap (this can be sited externally if preferred), all designed to make installation and servicing easier.
£250 cash back for any installer who purchased a Vortexblue blue flame boiler between 1st May 31st July 2022.
Eligibility
The £250 cashback is available on Grant VortexBlue oil boiler models only - Vortex yellow flame models are not eligible. This promotion is an installer promotion and it will be the responsibility of the installer to submit their claim. The promotional period is 1st May 2022 - 31st July 2022 and only VortexBlue boilers purchased during this timeframe will be eligible, until stocks last. Installers will need to install the eligible boiler and submit their claim by 31st October 2022.
Claims process
Customers will be able to claim their cashback once they purchase an eligible blue flame boiler through their local merchant and install and register the product. Once the boiler has been installed, the installer will need to complete the online claim form and supply all the information required, including a proof of purchase from their merchant. Grant UK will then pay the installer directly within 30 days of receiving a valid claim.
