Air conditioning, Ventilation and Heat pump installations, repairs and servicing in the North West, Lancashire, Cheshire and Yorkshire

Temptek Limited supply, install, service and repair all types of heat pumps such as air to water heat pumps, ground source heat pumps, Monobloc systems, Split type air to water heat pumps and ground source heat pumps for chilled water. We cover all UK locations such as Manchester, Liverpool, Preston, Chester, Lake district, Bolton, Lancashire, Merseyside, Cheshire, Cumbria, Wales, Staffordshire, Derbyshire, Yorkshire, Scotland, London, Cornwall.

Air to Water Heat Pumps

Air to water heat pump uses the refrigeration cycle to transfer heat (energy) from outside to inside it does this by the vapour compression cycle. This heat or energy is transferred to water via a heat exchanger the water passes through the heat exchanger and absorbs the heat this water is then sent to either under floor heating, fan coil units, radiators or a water cylinder. These systems are extremely energy efficient and cost alot less to run than a standard gas fired boiler or electric heaters. These systems continue to work even in extreme weather conditions meaning they suit the majority of locations accross the UK. Temptek specialise in installing, repairing and maintaining these types of systems we have the experience and knowledge to be able to work on these systems as we know what needs to be checked and cleaned regular. We are a relaible service provider that can offer our customers tailor made maintenance packages.

Ground Source Heat Pumps

Ground source heat pump is very similar to a air to water heat pump as it transfer heat or energy from one place and passes it on to another place by using the vapour compression cycle. A ground source heat pump use the ground as a heat source in the winter and a heat sink in the summer, this is done by circulating water underground by either burying a water loop or by drilling bore holes. The reason for this is simply that at a certain level under ground the temperature is always maintained regardless of the ambient temperature outside which makes this a relaible source for the heat pump system. Temptek offer repair and servicng on these systems with tailor made maintenance packages which include service visits by experienced and skilled engineers, detailed service reports, emergency call out options and extended warranties.

Commissioning Services

Heat pump systems include a refrigeration cycle and to work on refrigerants you must be FGAS qualified, as most ground source heat pumps and air to water heat pumps are installed by plumbing and heating companies they dont have this qualification so we offer our services once the installation is completed to attend site and make sure the refrigerant side of the system is set up correctly before the client signs off the project. 

Air to air heat pump

The heat pump is a heat-moving mechanism used from commercial to residential applications. The heat is absorbed from one area by an evaporator. Then it is released through a condenser in another area. The system if fitted with a switch over valve can reverse the cycle. Where the evaporator becomes the condenser and the condenser becomes the evaporator. This means the evaporator will produce heat and the condenser will produce cold air.

The liquid refrigerant enters the outdoor coil and draws heat from the surrounding air and is vaporised. The low pressure refrigerant is drawn into the compressor it then compressed to a high pressure and temperature - at this point it is then pumped from the compressor to the indoor unit. Because its temperature is greater than the indoor temperature heat is then released into the area. ( Remember heat always travels from hot to cold)

Geothermal heat pump systems

As we have explained above the air to air heat pumps system depends greatly on the outdoor temperature. To improve the efficiency of this kind of system some system some systems use heat exchanger coils or ground water. They are buried underground or the as an alternate option is in a body of water. Systems that uses this kind of configuration are called geothermal systems ( Sometimes called ground source heat pumps )

In cold or moderate climates it will be necessary to use antifreeze. So the water will not freeze in the cold temperatures in the heat exchanger, we use glycol or a brine mixture.

When installed correctly and are properly designed they can provide suitable water temperatures. When in the heating cycle, the liquid refrigerant flows through where the water to refrigerant heat exchanger. The refrigerant exchanges heat with the ground water circulating. The refrigerant absorbs the heat, and then boils to a low pressure vapour; the vaporised refrigerant is then drawn into the compressor. The vapour is compressed and then is discharged into the condenser. The vapour turns into liquid refrigerant. The liquid releases its heat into the room. The refrigerant then makes its way back to the heat exchanger to repeat the cycle. Also as the same with air to air it has a switch over valve, which in summer will allow it to remove heat from the room.

Resistance heaters for the cold weather used during winter. You would switch refrigerant circuit off and resistance heater turned on, with the room air fan.
