Description

Our pressure solar water heater can get 0.6Mpa hot water when u take shower. All the parts are the same to our non pressure solar water heater, except adding a heat exchanger copper coil inside the tank, we use water directly from copper coil as a closed loop to get the pressure the same as tap water. But our tank is still non-pressure type, so make sure vents open always as well. This type, we must install feeding tank, the principle is not the same as non pressure SWH, it just makes up some water into tank in case evaporating from vent. Because we don’t use water from tank, the tank just works as warmer to heat coil. So after days or years, water will be less and less, auto feeding tank will start to work and feed water into big tank automatically. But price of the type is much expensive. The price is included tank, tubes, feeding tank and frame structure, but Mg anode and electrical heater, controller are for your option. The advantage of this type is: it can bear 0.6Mpa pressure, so u can enjoy nice shower, also u can connect this type to your electrical boiler or gas heater directly.
