Atmos launches the high efficiency SolarCombi

Atmos Heating Systems unveil 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 50 deg C, 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.

When the tank water is below 50 deg C the diverter valve sends the pre-heated water through the boiler to top it up to 60 deg C.

The low volume of secondary water combined with the copper tube heat exchanger ensures protection against Legionella bacteria formation.

With the Inter and Multi condensing technology saving 35%, and the MonoSolar operation cutting energy consumption and costs by a further 15%, combined SolarCombi operation will save up to 50% in fuel costs, usage and related CO2 emissions.

Where larger volumes of hot water are required, the Atmos TwinSolar solution is the ideal choice.

This provides tank capacities of up to 330l unvented stainless steel or up to 210l vented copper, with one coil offering solar heat and the other connected directly to the existing boiler of an Atmos InterSystem HE26 boiler for maximum operating efficiency.

The MonoSolar and the TwinSolar are both designed for roof mounted or roof integrated installation.

In addition to working with the Atmos InterCombi or Multi boiler, the MonoSolar or the TwinSolar can be used to feed an existing vented or unvented hot water tank, if required.

As a closed circuit system, the MonoSolar is virtually maintenance free and, because the stored hot water transfers through a copper pipe heat exchanger, there is no risk of legionella.

Meanwhile, because the drain back system empties the solar collector, there is no risk of overheating or freezing.

Instead of an expansion vessel, the tank incorporates an air gap, and water automatically flows back into the tank's empty discharge space from the collector, eliminating the need for glycol antifreeze in the system.

Since 1976 Atmos Heating Systems has been designing and installing heating and hot water systems for homes and businesses.

The company is committed to the promotion of high quality, energy efficient and environmentally friendly solutions.

Its products are designed for the future and built to last.

They use the minimum of fossil fuels, thus reducing environmental pollution, and keeping running costs at rock bottom.

The company supplies high efficiency condensing gas boilers, together with solar hot water heating and underfloor heating.

Atmos is listed as an "Ethical Company" in the Good Shopping Guide.
