Hi, we had a Vital 111-S installed yesterday. The house is 100m2 and we have 8 radiators. The heat pump has used more energy than we usually use in a day in one hour, and the radiators are barely warm. The installer says this is normal. This is our first experience of heat pumps. It has been almost 24 hours and the radiators are lukewarm. Is this normal? Will the heat pump become more efficient when/if the house becomes warm? It will cost us €€€ in electricity to run the pump at this rate - simple converters were very inexpensive and more efficient! We are worried we have wasted over €10k. Many thanks
