Hello, 

 

we are in the middle of a air source heat pump installation and we applied to the Bus scheme to remove our gas boiler. We have a gas fireplace in the house that we mainly use as backup and extra comfort during the winter that we would like to keep, both for backup in case of blackout and due to funds available. The installers came today to cap the gas boiler told us that for the bus grant all other heat sources especially gas need to be removed. But during the survey and the whole process we were told we could keep it. We know it does not make financial sense, but we want to have a backup and the future plan is replacing it with a wood stove. 

on the Ofgem website it does say that all part of existent heating system must be removed, but the fireplace is not l technically part of the primary heating. 

does anyone have any similar experience? 

Thank you for any feedback you can provide. 

thanks

The requirements are set out here and include

 

(c)[the heat pump] replaces the heat generating components of the original heating system installed in that property (where applicable), other than any—

(i)supplementary electric heater, including any immersion heater,

(ii)circulation pump, or

(iii)solar thermal collector.

So the legal question which arises is whether the gas fireplace is part of 'the original heating system'.  That's an interesting question!

 

Our wood burning stove wasn't removed and I would argue, if challenged, that it's not part of 'the heating system'.  If that argument succeeds then it should also succeed for a gas fireplace.  

I would require them to reinstate and if they refuse to do so ask them point you to the legislation that requires them to remove.  They may well cave in at this point or direct you to guidance, which you can reject on the grounds that it is the primary legislation that matters.
