Good combination?
A heat pump works on electricity and it is the only one that you can produce yourself at home and quite simply - with photovoltaics. The problem is that when you need heating the most, there is the least solar energy, but even that has its solution and besides, you heat hot water all year round and that makes up 50% of the costs.
How do we reconcile this with our installation?
To maximize the use of photovoltaics for heat pump operation, we recommend:
- Heat DHW during the day from surplus photovoltaics, at night only to a minimum temperature, which will ensure DHW heated directly from photovoltaics for most of the year
- Supplement the storage tank with an electric coil, which will be heated by the ANTIK device for storing surplus photovoltaic inverter water, which will maximize the use of the photovoltaic power plant and at the same time save the heat pump.
- Parameterization of the equithermal curve directly according to photovoltaics, i.e. the greatest possible accumulation of heat during the day, meaning that the heat pump will heat more during the day than at night, which, in addition to using photovoltaics, also takes advantage of the fact that it is warmer during the day than at night and the heat pump operates more efficiently with a higher COP.
- We will recommend a virtual battery supplier that will allow you to use the summer surplus of photovoltaics in the winter when operating a heat pump. With the correct settings, the resulting power part of the electricity will be zero and you will only pay distribution fees.
- Smart connection of photovoltaics and heat pump using the Antik Smart home application, switching the heat pump and accumulating heat in the storage tank during a sunny day
Every installation involves proper sizing of the heat pump's output, matching it with the heating system, and setting the correct water flow rates. After inspecting your property, we will create a thermal engineering report with a calculation of the entire system design.
