local_fire_department Heating — Assens Fjernvarme
Assens Fjernvarme (established 1960) supplies biomass-based district heating to Assens town. In Glamsbjerg, Haarby and Aarup, local district heating companies supply heat. In rural areas, oil boilers and heat pumps are still common — switching to a heat pump makes good economic sense with available subsidies.

Frequently asked questions
about renovation in Assens.
Renovation in Assens primarily pays off through improved comfort and lower energy bills. Value appreciation is moderate, but energy savings — particularly when switching from an oil boiler — are clearly worthwhile.
Assens town is covered by Assens Fjernvarme (biomass). The other towns have local suppliers. In rural areas, oil boilers are common — here a heat pump is the best solution.
Trades prices in Assens are typically 10–15% lower than in Odense. Shorter waiting times and good local firms are a real advantage.
Roof, insulation (loft and basement), replacing the oil boiler with a heat pump, and windows are the four most important investments. On a farm property with a farmhouse, check the structure and moisture conditions in the basement and foundation thoroughly before starting.
Funen prices are slightly below the national average. A new roof costs 80,000–190,000 kr, energy windows 4,000–8,000 kr each and a bathroom 80,000–200,000 kr. Shorter waiting times and good local firms are a major advantage in Assens.
