1. Performance of household heat pump and battery
How does a hybrid heat pump perform compared to a condensing boiler, using identical demand patterns? What is the effect of installing an electric battery in a house?
An experimental setup at EnTranCe is used to run a heat pump following a near-real time demand pattern from a real house.
This project simulates the performance of a house with a heat pump and an electric battery system. The project intends to answer the following questions: .
What is the performance of a heat pump compared to a standard condensing boiler, in terms of:
CO2 emissions (kg CO2)
Cost (€)
Efficiency
What is the effect on net grid load when an electric battery system is installed in a house with solar panels?

Heat consumption
Electricity consumption and production
Near real-time measurements of electricity consumption and production at a real house with solar panels are taken.
The electricity demand of a heat pump located at EnTranCe is also measured.
A computer model simulates the net load on the electric grid on a one- minute basis.
A household electric battery system is modelled to determine its effect on net grid load.
Near-real time measurements of gas consumption at a real house are used to derive a heat pattern.
An experimental setup at EnTranCe runs a heat pump using this same demand pattern.
Near-real time software analyzes and displays data.
