Wood-burning oven for cooking, heat and hot water (Read 7013 times)

	Hello, we are investigating buying a wood-burning stove/oven with back boiler to supply heat to radiators and hot water. Does any know where you can buy them in Spain? Or do I have to import from the UK. I can't seem to find any around here.

	I don't know of any here - all the ones I have heard about and have installed have been imported. You could try Chimeneas Cardona in Alcanar - they have a big range of stoves but I have no idea if this includes ones with back boilers. One of the many thing to bear in mind, you can't use a wood burner with back boiler on a pressurised system (which is the norm in Spain) as the boilers are generally rated at below 2 bar operating pressure.

	Thanks, Nigel. About the pressurised system you are referring to the water system? The stove we are looking at operates at 3 bar. Cactus Jack, we would use electric in summer, not the wood burner.

	Hi Nigel, just checked out Chimeneas Cardona on line and they do have they type of stove we are looking at. So we will go on Saturday. Thanks!

	A few pointers..... 1. You need a water tank with an indirect heating coil in it if you want to use the woodburner for hot water. The tank (the hot water part) you need will need to be able to operate at the pressure of your water supply. The coil will be designed to operate under pressure. English copper cylinders are designed to operate at 1 bar and will swell up like a balloon if you pressurize them. 2. You will need some sort of 3 way valve (normally operated by a thermostat on the hot water tank) to switch the flow from heating to hot water. 3. You need to know the MAXIMUM working pressure of the boiler in the woodburner so you can decide if you can operate with a closed system and an expansion vessel or if you will need to install an open vented system. 4. You will need a pump and a thermostat connected to the woodburner and always powered up so that the water circulates when the wood burner is running and reaches a certain temperature - if not then you may end up boiling the water in the heating system and damaging the connections to the woodburner or worse!
