You could simply connect a new radiator to an existing central heating system. Check with your conservatory supplier or local building officers to make sure this is allowed. If you have an efficient boiler already then this method will have a very low running cost.

For optimum heat circulation it is suggested to install the radiator near the dwarf wall though this is not always possible nor indeed convenient. tiled conservatory roof cost
