7. es in both water and energy usage We d like to explain how it s so different from other hot water systems and why it s setting completely new standards To fully appreciate the difference and the substantial benefits offered by the technology used in this water heater we need to start off by comparing the main deficiencies of traditional hot water systems Heating water the traditional way Traditional centralised hot water services consume continuous energy to heat water and then maintain it at a defined thermostat controlled temperature ready for when it s wanted Typically the water heater is located away from where the water is wanted relying on lengths of pipe to deliver the water Energy is therefore wasted keeping quite a large volume of water at a stable temperature often at a higher temperature than would ever be used But that s not all water is wasted every time a hot water tap is turned on That s because you need to let the water run until the water held in the pipes has made way for the hot water you want coming from the water heater The overall result is quite inefficient usage of power together with wastage of water The MicroHeat difference The engineers at MicroHeat set out to create something completely different from existing methods of providing hot water a highly efficient new method of heating water that would address the wastage of valuable resources ener
