Air Source Heat Pumps work on the basis of extracting heat from the air, which is then converted into useable heat for the home. Heat Source Pumps are extremely versatile and
can be used in a number of different applications.
Easy to install, much cheaper to run than Gas, LPG, Oil or Electric.
For hot water only, a relatively small air source heat pump of 8kw can be used. On a ratio
estimate of COP 4/1, this would use only 2kw while operating at it`s optimum.
This figure of COP 4/1 is not consistant throughout the year and is seasonally affected.
For higher water use, a 12kw air source unit can be used.
As with the solar package, Mistral always recommend a back up system (biomass, gas or oil)
to maintain hot water requirements at a satisfactory level throughout the year.
These provide fast recovery products for hot water.
Whether you choose to install Solar Panels or Air Source Pumps to provide hot water, both systems are regarded as long term solutions. Both also have their slight advantages and disadvantages to each other even taking into account the different type of installations.
It is clear that either system will operate at their highest efficiency during the better weather months of the year and we think customers should take advantage of this window of opportunity.
These systems may achieve high rates of return for perhaps 10 months of the year, but you should always take into account the need for a satisfactory back up system to get through
the worst months comfortably.
