Wood Boiler Storage Tank Sizing

Heat storage is a condition of some wood boiler warranties and epa approvals.

Wood boiler storage tank sizing.

A heat storage system is an important component of modern wood boiler systems. Fully automatic wood pellet and wood chip boilers can be installed without thermal buffer tanks in some applications but the use of thermal storage is generally advised for reducing burner starts reducing wear on cycling parts decreasing emissions and the need for. Heat is supplied by the boiler when there is a demand by the house. By absorbing extra heat generated during the burn cycle heat storage allows wood boilers to operate with less tending lower emissions and higher efficiency.

The heat storage acts as a buffer between the boiler output and the house s heat demand. When demand falls then heat is diverted to the storage tank. How a heat storage system works. Offers two levels of insulation for every size of wood burning heat storage tank it manufactures.

A water storage system takes any excess output of the boiler and stores it in water tanks. Then when this heat is needed it can be drawn from those tanks instead of directly from the boiler. Optimized combustion by allowing the boiler to run wide open. Compatibility of hydroflex hydroflex hot water tanks can be used with any wood boiler commercially available tanks are also available with a double insulation kit for greater than 24 r value.

When wood has burned out heat is supplied from the storage. A fire burns most efficiently when it is burning very fast and very hot but your home s needs are different and the heat you use must be sustained over many hours. Heavy tank insulation holds stored heat allowing for 24 hours or more between burn cycles. More efficient boiler operation less wood less pollution less creosote.

The benefits to such a system are many but include. For instance during a typical winter day many wood boilers used with heat storage are loaded once in a 24 hour period.
