air source heat pumps

Despite its size, the Terra CL air source heat pump is one of the quietest air source heat pumps on the market.  Its fully thermally insulated casing separates the machine's interior from the outside environment.  This results in both considerable sound insulation and optimised thermal insulation. 

Air source heat pumps are suitable for retro-fitting into an existing building or where there is insufficient space for laying a trench system for pipe.  Installation inconvenience is considerably reduced.

If you live in an area which suffers higher levels of frost combined with high air moisture content, air source heat pumps should be avoided.  Geography really does matter.  A combination of high moisture and low temperatures can considerably reduce an air source heat pump's efficiency; it can spend too much time de-frosting itself rather than heating your home. 

The Terra CL Air Source Heat Pump is one of the most efficient on the UK market.  The reason for this is due to the size of its evaporator heat exchanger which is larger than many conventional models.  For its size, it is remarkably quiet - it is one of the quietest on the market - as low as 31 dB(A)
