Pressurised Hot Water System

An unvented system works by pressurising the main hot water cylinder in order to output the hot water feed at high pressure with good flow. The rising main is connected directly to the calorifier water heater or plate heat exchanger. Its partner the HeatStream Electric PLUS meets the demands of larger properties where off-peak electricity and a traditional primary heat source such as a boiler or a district heating is available. If theres a fault with the thermostat the water will continue heating and may eventually reach 100C and boil.
