      How many solar thermodynamic panels do I need for 170 sqm house with 5 occupants for both hot water and central heating purpose?

      The most commonly installed thermodynamic sized system is for a four-person household that would need one panel for a 250-litre cylinder. It would cost around £5,500 to install.

      I’d personally use that investment for PV with a hot-water heat exchanger that doesn’t burn electricity to run the compressor costing you £120.00 per year.

      This is why we don’t promote thermodynamic systems.

      Hope this helps.
