Pressurised versus Non-pressurised

In a pressurized system the hot water storage tank is directly connected to the cold water supply. For that reason the cold and hot water pressure is always the same...

In a non-pressure system, the pressure at the hot water outlet depends on gravity, this means the height between the hot water tank and the hot water outlet...

MONTHLY SAVING

8.8 MWh annual energy production

If you used all the energy produced as hot water, the saving in electricity costs would be about 24,000.- THB per year. Reduction in greenhouse gas per year: 5.3 Tonnes of CO2.
