Hello, we also installed our own Rayburn Royal, bought an old one on ebay for £80, and resurrected it with approx £150 of spares. Works perfectly for heating and cooking, decided to remove the back boiler as it was never intended for heating water. If you embark on a similar restoration project, feel free to drop us a line, more than happy to assist and advise on restoration. I think I can assemble rusty old Rayburns blindfolded now.
