USING A VILLAGER STOVE FOR CENTRAL HEATING Villager offers two models (AHI and ALI) with integral back boilers with a maximum output of approximately 15 kW. This is sufficient to run central heating and hot water in quite a large house. Most other models can be fitted with a back boiler (either mild steel or stainless steel). AH and AL models have an output of approximately 10 kW to water which is adequate to run central heating in a smaller house (hot water plus three or four radiators) . The traditional arrangement for solid fuel central heating is to have a primary circuit which thermo-siphons via the hot water tank. A second circuit is tapped off to feed radiators with a pump on the return which is controlled by a pipe thermostat on the return fairly close to the boiler. The thermostat ensures that when the fire dies down it avoids circulating cold water through the boiler which cools the fire further and can cause condensation on the boiler which reduces the boiler's life. Sealed systems which are normal in gas and oil-fired systems (thermostatically controlled boilers) can be used but the system must be very carefully designed. Open systems which require a header tank and vent are recommended. Alternatives to the traditional system are: 1. If domestic hot water is already available from another source (electric tank) more radiators could be added to the system. 2. A fully pumped system can be used but radiators should be over-sized to allow for overheating. The wood fired boiler can be linked as the master or slave to another boiler fired by gas or oil, or even with a solar heating system in the case of water heating only.
