The objective of the project BioSol is to develop a new concept for heat transfer from a stove to a water-based heating system for domestic hot water preparation and space heating. The heat demand can thereby be covered 100% by renewable energy in terms of firewood and solar energy.
Modern houses are however built with a low energy or passive house standard, which creates a mismatch between the instant heat power delivered by conventionally sized wood stoves or fireplaces and the heat demand in the area that is directly exposed to the heat source. Many house owners install a wood stove to fight cold weather and because indoor comfort. The stove delivers more heat to the room than required. This challenge can be solved by transferring excess heat to a water-based heating system and an accumulator or a heat store.
BioSol is a IPN project with 4 partners: Stansefabrikken, Frost Produkt, Jøtul and Aventa. All partners provide significant inputs to the new system, which consists of 3 major elements: a wood stove insert from Jøtul, a new-designed water jacket and a heat store (Stansefabrikken) with a tailor-made system controller from Aventa. Frost Produkt is industrial design partner.
Qualitative and quantitative tests are conducted in factory and lab. The market interest for a combined solution with solar energy and a wood stove is already considerable. Full-scale installations in detached houses will be followed up with system monitoring.
