A prototype of the new HEAT-INSYDE heat battery will be demonstrated in three European countries with different climates

Temperatures: 4°C to 22°C

Hours of sunlight per day: 2 to 7

Temperatures: 7°C to 25°C

Hours of sunlight per day: 5 to 12

Temperatures: -3°C to 18°C

Hours of sunlight per day: 1 to 8

Eindhoven, Netherlands

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.

Saint-Paul-lès-Durance, France

One house has been selected in the area of Saint-Paul-lès-Durance. The demonstration house, recently built by Tecobat, has a wooden frame structure with concrete elements. The house has a large roof surface area for PV and solar collectors. The location is typical for a Mediterranean climate in an area with a low population density. A stand-alone solution connected to the electric grid is the only option as a district heat network is not present. Here, the hybrid combination of the closed loop system with an electric heat pump is considered, aiming to cover both the space heating and hot tap water demand.

Gdańsk, Poland

One privately owned residential building has been chosen in Gdańsk.  It is a row house with 3 stories, constructed around 1940 and renovated in 2012 (insulation layer of EPS added to the external walls and new double glazed plastic windows installed). The building is connected to a heating grid, generated by a power plant. The heating system is composed from radiators installed in the basement, a floor and attic. The ground floor has a floor heating system (based on water pipes on the floor). No heat pump or solar collectors have currently been installed. Here the heat battery will focus on peak loads during cold winter days and tap water demand to increase the share of renewable energy.
