How much hot water do these panels produce?

They believe that they offer 100% of the hot water requirements for commercial and domestic premises, underfloor heating, swimming pools, and can make a contribution to conventional central heating. To avoid any risk of legionella, they come with a built-in immersion that uses electricity to boost the water to 60 degrees every now and then.

How do they compare with solar thermal?

Thermodynamic panels heat a refrigerant, where solar thermal panels heat water in the panels. This allows the thermodynamic panels to extract heat from the atmosphere, whereas solar panels are highly dependent on heat from the sun. At -22 degrees centigrade, the refrigerant enters the panel, so that relative warmth from the air can be absorbed even on cold winter days.

Solar thermal panels offer the best performance on roofs that face between southwest and southeast. Thermodynamic panels can be placed on the roof or a wall. It is best not to have them facing northwest or north, but they don’t have to face south.
