Atmos Heating Systems, the low carbon heating specialist, has unveiled its SolarCombi system which can cut fuel costs and CO2 emissions by 50% compared to conventional gas heating systems.
The SolarCombi presents two installation options, bringing together the Atmos MonoSolar drain-back system with either the Atmos Inter or Multi range of high efficiency condensing gas boilers.  The MonoSolar features a 100 litre insulated thermal storage tank, complete with an integral copper tube heat exchanger, energy-saving variable speed pump and electronic control module, and a drain back solar collector. Storage tank water circulates around the solar collector, absorbing heat from the sun which is transferred via the heat exchanger to tap water to offer savings of up to 1,500 kWh of gas energy per year.
The MonoSolar system includes a simple non-electric diverter valve, when the tank is above 50ºC, the diverter valve activates to bypass the boiler and send water straight to the tap. This reduces the boiler’s operational time and hence reduces gas consumption.
