Hot Water Boiler Piping Zone Valves and Wiring Diagrams

Hot Water Boiler Piping Zone Valves - Boiler piping zone valves are used for zoning hot water systems where multiple zones are needed.Hot water system zoning can also reduce energy cost because hot water heat zones which are not needed can be shut down thereby reducing boiler runtime to provide hot water heat for those specific zones. Zoning a hot water boiler system can be done by using these

Solar water heating - Wikipedia

A differential controller senses temperature differences between water leaving the solar collector and the water in the storage tank near the heat exchanger. The controller starts the pump when the water in the collector is sufficiently about 810 °C warmer than the water in the tank, and stops it when the temperature difference reaches 3

Condensing boiler - Wikipedia

Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by condensing water vapour in the exhaust gases and so recovering its latent heat of vaporisation, which would otherwise have been wasted.This condensed vapour leaves the system in liquid form, via a drain.
