Heat Pumps

Heat pumps offer an extremely energy efficient approach to heating a property. Their efficiency is measured by a Coefficient of Performance (COP) which indicates how much heat they can create in relation to how much electricity they require to operate. Some heat pumps can achieve a COP of over 5 which means for every 1kW of electricity used to operate, they can create 5kW of heat.
There are a couple of different types of heat pump available to suit different situations, the main ones being Air Source (ASHP) and Ground Source (GSHP). Due to the nature of the UK building stock, ASHP’s are the most common but, for properties in particular situations, we can also offer Water Source Heat Pumps (WSHP).
The original Ochsner company was founded in 1872 and are our heat pump manufacturer of choice. Based in Austria, they are internationally ranked as one of the technology leaders in the industry and produce some of the most sophisticated, silent and energy efficient heat pumps on the market.

FAQ’s
Do I need planning permission?
Installations are usually covered by permitted development rights meaning planning permission is not required. Some exceptions to this rule are for listed buildings, conservation areas, national parks etc. It is always advisable to contact your Local Authority prior to installing a system to be sure
How much maintenance is required?
Typically you will need to have a system serviced annually by a qualified engineer and the glycol changed every 5 years
Are they noisy?
There is some noise associated with the fan on a heat pump but it is relatively low, around the same level of volume as a fridge. The noise level is identified during the design stage, so that the heat pump can be positioned accordingly so that it does not cause a nuisance to either yourself or your neighbours.
Is my property suitable?
A well-insulated property is usually required for a heat pump to work at it’s optimum efficiency. Most buildings have sufficient space outside to locate an air source heat pump but ground source and water source require additional space.
Do they work in cold weather?
Simply put, yes. A correctly sized system will keep you warm all year long. Heat pumps have been used in Europe for decades. The standard outside design temperature used in Austria is -14C compared to the UK average of -4C.
Do I need a backup/supplementary system?
No. A correctly designed system will meet all of your heating requirements.
