Four different houses have been selected in the residential area ‘t Ven in Eindhoven, representing different types of end-users: renters and owners. These houses have been built between 1970-1980, insulated afterwards and have an estimated heating demand of 20 GJ/year. Two are rented houses, owned by TRUDO. The other two houses are privately-owned, with the Eindhoven municipality as the contact point. This location considers both a low-temperature heating grid and the hybrid heat pump combination connected to the electric grid. Here the heat battery will focus on peak loads during cold winter days and tap water demands.
