PELLET STOVES IN PARISH COMMUNITY CENTRES / CEMETERY FACILITIES
Pellet stoves can be an excellent alternative to boilers fired by oil or gas in churches, located outside areas with district heating and where installing a heat pump isn’t possible. However, in smaller cemetery facilities and parish community centres with electric heating it is recommended to examine the possibility of mounting an air-air heat pump.
There are pellet stove systems that are virtually fully automated but most wood pellet boilers require a certain degree of effort handling the pellets, cleaning and inspection. Most of the work takes place during normal working hours, but assistance at other times might be needed.
Where should the pellet stove be placed?
Before the purchase of a wood pellet stoves, it is important to think of both the location of the boiler room and storage of wood pellets. Consider that the handling of the pills should be easy, and that the pills can be stored dry. Unless there is a suitable back entrance or shed near the buildings to store the wood pelles, there is a risk that a new suitable boiler room must be built.
Requirements for boiler room and storage
When installing a wood pellet boiler, certain requirements regarding the boiler room and storage must be met (fire codes, etc.). An existing chimney must be checked for suitability before the boiler is installed.
It is recommendable that pellet storage is kept close to the boiler room to facilitate easy loading of pellets. Wood pellet boilers are available on the market that automatically suck the pellets from a silo (which can easily be established in an existing building or container). However, a screw conveyor is usually necessary for loading (which requires a slightly higher silo with a conical bottom and discharge below). Manual refilling from bags is possible as well, if necessary manpower is available.
The price of pellets varies considerably, as does the quality. Heating with wood pellets is generally cheap. The prise is typically 40 to 45 øre per kWh heat.
Investment costs vary greatly. There are big price variations on individual brands, including different functions. Some are almost fully automated, while others require more manual effort. Extra costs for boiler room, chimney and storage room also vary greatly. It is recommended that more than one specified tender is ordered. If major structural changes are required, an architect must usually be involved.
