Solar’s solution was to install two air/water heat pumps in a cascade solution, where one heat pump is activated at a time to minimise wear and tear. A buffer and an additional hot water tank were also installed to ensure a continuous supply of hot water. Due to the special layout of the system, an ordinary hot water tank would risk the heat being flushed out and the electric heating in the tank would heat up the return pipe in the heating system. The problem was overcome by choosing a hot water tank with a heating element at the top. As well as ensuring the correct capacity in the heat pumps, Solar also successfully addressed the special conditions pertaining to the hot water supply.
”As we run a very busy business, we really value Solar’s competent advice and fast assistance with the calculations. Their flexibility in finding the best solution is also a great asset,” says Allan Stokbæk.
Schrøder has since checked with the customer and the system is running smoothly. The customer no longer has the hassle of filling and cleaning the pellet boiler stove – and savings are even expected at the end of the year.
