Heat pumps for professional projects

You are here

Dimplex offer a large range of commercial air and ground source heat pumps, suitable for both heating and cooling, which offer low carbon solutions to help pass building and planning regulations. A hydronic system is suitable for use with underfloor systems, which due to their large surface areas can run at lower flow temperatures compared to a VRF or Ducted system. This makes the system more efficient and gives benefits during the design stages and ongoing costs. The SI TU and SI TE ranges provide the ideal solution for buildings with high heat consumption, as a centralised system can provide a building-wide heating solution – ideal for offices, schools and multiple occupancy buildings.With the widest range of heat pumps in the UK, no matter the energy source (air or ground), there will be a solution in the Dimplex range ideally suited to your customer's needs.

Commercial air source heat pumps

How does an air source heat pump work?

Air source heat pumps work by efficiently heating or cooling a building, using the ambient air as a heat sink and ‘pumping’ it to higher grade for use inside the building. They are able to produce more energy than they consume to deliver a very efficient form of heating, and by using the same technology employed in a refrigerator, the heat pump absorbs heat from the outside and raises its temperature to a level suitable for heating. As heat pumps work much more efficiently at lower temperatures than a traditional boiler supplied heating system, they are more suitable for underfloor heating systems, Dimplex “SmartRad” fan-assisted radiators, or large radiators that can deliver the required heat at lower temperatures. Heat pumps can also provide hot water, which is stored in a storage cylinder.

Air source heat pumps - heating from the air

Air source heat pumps use the latent heat in the outside air to heat a building and provide hot water. As air is freely available all around us, air source heat pumps have the advantage of relatively low installation costs and minimal space requirements as they are installed outdoors. Because the source of heat – the air – is abundantly available all around us, air source heat pumps can reduce energy costs, especially when compared to oil and LPG heating systems, plus they’re virtually maintenance free. Our relatively mild winter temperatures in the UK mean a properly installed air source heat pump system can achieve excellent levels of efficiency and performance throughout the year.

Flexibility

Dimplex heat pumps can be combined with a wide number of fully compatible system accessories, including buffer tanks and domestic hot water systems to provide complete flexibility in terms of system design. To simplify specification and installation a number of our heat pumps are also offered in packages which include heat-pump ready cylinders and/or buffer tanks, and all the components required to install a standard domestic system.

Installer benefits of Air Source heat pumps

  • Hydronic circulation system offers benefits over VRF systems such as practical limit and heat recovery for hotels and other applications
  • Simple to install, making them popular on new build applications as they still have high efficiencies to help pass building and planning regulations
  • Range of internal units are ideal for situations where outside space is at a premium or when the building design or a potential  risk of vandalism requires installation in a secure internal space
  • Eligible for the Non-domestic RHI in mainland UK offering the system owner payments

Control

The comprehensive Dimplex heat pump manager provides complete system control over multiple heating and hot water circuits and, where needed, cooling functions. Self-explanatory display text provides simple operation, allowing your customers complete control over their heating and hot water system.

Commercial ground source heat pumps

How does a ground source heat pump work?

Ground source heat pumps use the solar energy stored in the ground to heat a building and provide hot water. They extract the heat from the earth using collectors – consisting of plastic pipes – buried underground. Because the source of heat is free, ground source heat pumps can reduce energy costs, especially when compared to oil and LPG heating systems, plus they’re virtually maintenance free. A particular benefit of ground source heat pumps is that even at a depth of 1m, the ground maintains a fairly constant temperature, so the systems perform well all year round.

How does a ground source heat pump work?

Ground source heat pumps are able to produce more energy than they consume to deliver a very efficient form of heating. By using the same technology employed in your refrigerator, the heat pump absorbs heat stored in the ground and raises its temperature to a level suitable for heating. The heat is collected from the ground using a series of buried pipes, through which a fluid is circulated, attracting the heat energy and transferring it into the heat pump. Ground source heat pumps are normally located inside the main building – often in a utility room, basement or small plant room and connected to the central heating system inside. Heat pumps work much more efficiently at lower temperatures than a boiler supplied heating system, so they are suitable for underfloor heating systems, Dimplex “SmartRad” fan-assisted radiators, or large radiators that can deliver heat at low temperatures. Heat pumps also provide hot water, which is stored in a storage cylinder.

Benefits of ground source heat pumps

  • Can efficiently heat or cool a building using the ground as a heat sink whose temperature remains relatively stable throughout the heating and cooling seasons. Since a heat pump’s efficiency depends upon the difference between the source and the supply temperature, GSHP give excellent efficiencies that are second-to-none when trying to pass Building and Planning regulations
  • Are the hidden renewable technology, which doesn’t have any visible or audible parts outside the building and therefore also has low maintenance requirements
  • Extracts heating or cooling from the ground via either, horizontal collectors, vertical boreholes or a submerged pipe in a lake or river
  • Useful heating or cooling extracted from the ground is then passed on to a hydronic heating system for use in space heating or hot water
  • Eligible for the Non-domestic RHI offering in mainland UK
