I need 2 new storage heaters fitted, one in the lounge which needs to have a panel heater built within I like the Quantam as it has controls & programming

The hall one can be a bog standard replacement

We are on Comfort Heating but dont have a booster switch for the hot water so when it is gone it is gone. I have been advised its possible to add this as there is space in the junction box for this to be added.
