Hi,

Im currently in the middle of a new build and am looking advice on my heating system. It is a 3000sq ft chalet bungalow (with 1st floor) with underfloor heating on the ground floor and radiators on the upper floor. I have allowed for a wood burning stove in my sunroom with a back boiler that was intended to heat the water and upstairs radiators and linked in with my oil heading with condensing boiler serving the UFH downstairs. Is this the most practical arrangement for this type type of system or can you suggest alternatives. I have a mains pressurised system being fitted but my plumber has informed me that my back boiler isn't pressurised... is this normal?

Thanks for you help and any feedback will be greatly appreciated
