Check the listing for details. Solar Hot Water Gas Heater Thermostatic Diverting Tempering Mixing Valve Mixer. Condition: New. Listed at 214.00 USD. Solar Gas Kit with Adjustable Input & Output The Solar Gas kit is fully assembled and tested in the factory. It consists of:InletThermostatic diverting valve 1” Male with adjustable diverting temperature from 38°C up to 54°C by means of a graduated knob – Kvs 3.5Solar check valve and filter built in the connection pipe to the solar storage tankT-shaped swivel connection to the gas heater OutletAnti scald thermostatic mixing valve 1” Male – Kvs 2.5. Control of the user temperature adjustable by means of a knob from 35°C up to 60°CSolar check valve and filter built in the connection pipe to the cold water How It WorkThe adjustable solar gas kit allows to manage automatically and to exploit at its best the thermal energy delivered by a thermal solar system and to supply hot domestic water for end user, at a controlled temperature. The adjustable diverting valve allows to maximize the exploitation because the diverting temperature can be fitted on the installation features, on its geographic location and on users practice. It also possible to change the diverting temperature in accordance with the seasons of the year: lower temperature in summer time or higher temperature in winter time The kit, supplied in a suitable and smart EPP insulating box, works in two ways: 1) In case the water temperature coming from solar storage tank is high enough, for example in summer, the first device of the kit, the adjustable thermostatic diverting valve, at the selected temperature such as 42°C, diverts the fluid towards the thermostatic mixing valve, so avoiding ineffective gas heater starting. Then the mixing valve mixes the fluid with cold water from mains, up to a temperature pre-setted. 2) In winter water temperature in solar water tank is low (lower then the selected temperature such as 48°C) the first valve diverts in a proportinal way the pre-heated fluid towards the gas heater, so exploiting to the maximum its energy and reducing to the minimum the gas heater working time. The anti-scald thermostatic mixing valve, placed at the outlet of the kit, always controls and restricts the water temperature to the users. The anti-scald function automatically stops the hot water flow in case of failure in the cold water line
