Atmos Combinair

The Atmos Combinair is a combi with a remarkable difference. Condensing boilers have pushed gas boiler efficiencies from 78% to 91%, a notable improvement. The Atmos Combinair takes this way beyond the boundary of 100% to as much as 130%. Yes that means you get 30% more energy out than what you put in.

How is this possible?

First there is the Atmos Combipact, a 27kW condensing gas combination boiler for heating and hot water. The SEDBUK efficiency is 91%, and classes in the top A rating. However if used with a low temperature heating system such as underfloor heating running at 40 deg C, the efficiency rises to 98% so that virtually all the heat is extracted from the gas.

Then there is the air source heat pump. All modern houses have air extract systems, which extract warm stale air from the kitchen, bathroom and other parts of the house. The boiler has burned gas to heat up this air, which is then thrown away. The Combinair heat pump draws in all this extract air and cools it, thus recovering 100% of the heat that would have otherwise been lost to atmosphere. Additional heat is taken from the outside air, so that the 665 Watts of electrical energy absorbed by the heat pump produces 2,500 Watts of heat energy. This is an astonishing efficiency of 378%. Put the two together and an overall efficiency of 130% is the result.

Benefits:

• Maximum CO₂ saving due to combination of ASHP with gas combination boiler
• Solar Compatible
• Ideal for Code for Sustainable Homes - Level 3 & 4
• 100% of ventilation heat is recovered.
