On topic, but slightly different.
We have to change gas combo boiler (old). We have small south facing roof area that could only fit few panels.
So was thinking could add 2x Solar thermals, new boiler and new 2x coil tank?
This is all to help reduce gas for hot water only? (dunno if will even help much financially??) (3 bathrooms, 4 bed, 4 people house).
2nd thought, could I add several PVs, and use it to virtually direct drive electric immersion in tank? Or am I being plain daft????!! Thanks
