What are heat pumps ?
Heat pumps are systems that draw energy from the environment and then pump it into your home, office or hot water system. There are various different types of Heat pumps. Heat pumps are becoming more common in residential and commercial environments because of the huge efficiency gains they give over conventional heating systems. In fact if you are on an oil based heating system you should investigate a heat pump today, we carryout FREE surveys and quotations for heat pumps in Devon, Cornwall and Somerset.
Whats all the fuss about ?
The reason that heat pumps are growing in popularity is because all our fuel bills are rising and heat pumps are very efficient. It is possible to get as much as 8Kw of heat from 1Kw of electricity put into the devices. Also some of the heat pumps qualify for the Renewable heat incentive (RHI) scheme this means you get paid for your hot water generation just like the feed in tariff for solar panels. We explain all about the RHI on our solar thermal page.
Air to Water heat pumps
These are the most common form of heat pumps. Heat is removed from the air outside your home or office and passed through a heat exchanger which heats the water in your cylinder or central heating system. Yes the system works even if its freezing outside. However cold it appears to be there is still heat outside that can be used. In fact these units are incredibly popular in Scandinavia where it does get a little chilly. There are different types of unit depending ob whether you wish to upgrade your existing property or incorporate into the building from new. These two types of heat pump are shown below.
Brine to Water Heat pumps (Ground Source heat pumps)
These are the pumps that most people have heard of. They use a series of pipes in the grounds of the property to draw heat from the soil. Because the soil is at a more constant temperature these systems tend to be more efficient than air source heat pumps but of course have the limitation that you do need a reasonable area of land around the property to install the pipe work. The price tends to be higher for these systems due to the work involved in installing the ground pipe loops. However this is more than offset by the increase in efficiency of the system over air source systems.
Ground Water heat pump
This is our favorite type of heat pump. These heat pumps draw water from standing water around the property such as a lake, pond or well. Water holds onto its heat very effectively and so these systems provide a large almost limitless amount of energy for the heat pump. The only down side of course is you need some water near your home or office. These systems can also be used on bore whole installations. Of all the heat pump systems these are the most efficient.
Design of your air source system
Design of the air source system is essential to optimise your investment. If fitting into an existing property the whole central heating and hot water system needs to be assessed to ensure they are suitable. Fortunately our surveyors are fully trained to do this for you and we offer this service to all our customers in Devon Cornwall and Somerset this service absolutely FREE.
