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. Open vented 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, It is always advisable to have part of the system operating on gravity circulation so that in the event of a power or pump failure the energy from the boiler can still be dissipated reducing the risk of damage to the boiler 2. 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. Solar/solid fuel hot water heater is best achieved with a dual circuit tank |
