Pressurised Hot Water - Megaflo Unvented Hot Water

Pressurised Hot Water . In traditional open vented systems, as the water is heated, it simply expands into the water tank in the loft. If there's a fault with the thermostat, the water will continue heating and may eventually reach 100°C, and boil. The boiling water will turn to steam and evaporate into the atmosphere.
