Heat Pumps

Heat Pumps in Perthshire, Edinburgh and throughout Scotland

Glendevon Energy have been advising, supplying and installing air source heat pumps and ground source heat pumps since 2005.  We have customers in Perthshire, Edinburgh and across Scotland, extensive experience of both domestic and small commercial projects, and would be delighted to hear from you.  

Regions we cover include:  Perth and Kinross, Fife, Angus, Stirling, Falkirk, Clackmannanshire, Aberdeenshire, Lanarkshire, Argyll & Bute, Dumfries and Galloway, Dundee, Ayrshire, Dunbartonshire, Lothian, Edinburgh, Glasgow and the borders.  

We offer a full technical service, from design and specification, through to sales, installation and maintainance, and will ensure that you have the right product for the right job.  

As an MCS accredited company we deliver systems compatible with the Domestic RHI , and support you with your application.  We also install compliant systems for Non Domestic RHI customers with commercial/ industrial applications.    Our servicing and aftercare department provide an efficient, effective and timely service, facilitating high performing systems and long term relationships with customers.  

Typically Heat Pumps are best suited to well insulated, low energy buildings with low temperature distribution systems such as UFH and low temperature radiators/ fan coils.  They will work with traditional radiators (though these need to be over sized compared to that for an oil or gas boiler for the best efficiency), and may be retrofitted to existing buildings.

If retrofitting it may be beneficial to dock with an auxiliary boiler such as existing oil or gas, to 'top up' when conditions get beyond those which the heat pump can tolerate efficiently.
 
Situations to avoid include: poorly insulated and draughty houses; sporadic heating (eg village halls used infrequently); and micro-bore (biro thick) heating pipes.
 
Most domestic properties are on a single phase (230V) electrical supply, which restricts the heat pump output to around 16kW, however it is possible to cascade two heat pumps to increase single phase capacity. Three phase supplies enable heat pump outputs to increase to 60kW per unit.
 
GSHP - Ground source heat pumps usually require 1 borehole per 5kW of output or a horizontal trench area around 1.5-2 x the heated floor area of the property. Horizontal trenches are just as efficient as boreholes but a lot less expensive in most cases (ie good boulder free top soil).
 
ASHP - Air source heat pumps save on the costs and disruption of ground works and are a very popular solution for the domestic market.  Although they run slightly less efficiently than ground source heat pumps they can still be a very effecient system in the UK depending on the outside temperatures and location.  
 
Weather Compensation controls are standard with our heat pumps and can increase efficiency and lower running costs. This works by adjusting the flow temperature and output of the heat pump to the external weather conditions in order to maintain the set internal temperature at optimal efficiency.
 
'Set-back' temperature settings enable a reduced output during 'off' times so the system does not have to re-heat from cold. For example, a screeded UFH floor has a large thermal mass/slow response time when heating from cold; set back enables a faster response.
 

Key Considerations:

  • Annual energy demand (kWh) and range of output required (kW)
  • Number and types of heating circuits
  • Electrical supply (230V/3-phase)
  • Location and size of boiler room
  • Ground area, soil/rock type or location of out door air unit.
  • Building warrant and planning considerations
  • District Network Operator (DNO) electrical supply confirmation
  • Funding options
 
For examples of the systems our customers have opted for please see Case Studies. For more details of the specific products please refer to the ASHP or GSHP sections.
