Ground Source Heat Pumps

Your energy consumption for heating could be lowered up to 75% compared to direct electricity with the use of a ground source heat pump.

Ground Source Heat Pumps

NIBE ground source heat pumps

NIBE produces 12 different types of ground source heat pumps, ranging from 5 kW to 60 kW that can cater  for the smallest residential property to light commercial buildings. By using a cascade connection it is possible to achieve an output of 540 kW. Here are some of the most popular models:

F1145   

NIBE F1145

NIBE F1145 is a ground source heat pump for heating single and multi-family houses and industrial buildings.

It has a high coefficient of performance (CoP) which provides savings and shorter payback times and can deliver high flow temperatures of up to 65°C.

It's easy to operate with a multi-colour display with clear user instructions and multi-language support.

The F1345 heat pump has an elegant design and is very quiet in operation.

    

Stiebel Eltron ground source heat pumps

Stiebel Eltron has been producing highly efficient electrical appliances since 1924, in the fields of domestic hot water, renewables, air conditioning and room heating. Headquartered in Holzminden, Germany, the company runs an Energy Campus – a flagship project for sustainable construction housing its training and communication centre. This Plus Energy building generates more energy than it consumes and is a great demonstration of the Stiebel Eltron commitment to energy efficiency.

The company takes great pride in the efficiency of its heat pumps and is one of the few companies to achieve a coefficient of performance (CoP) of up to 5 – meaning from one part electricity, they generate up to five parts heat. This categorises them in the higher energy efficiency class of A++/A+++ (at flow temperatures of 55°C/35°C).

Stiebel Eltron WPC ground source heat pump   

WPC S

5kW, 7kW, 10kW and 13kW capacity models

The WPC S is compact in size but exemplary in efficiency, achieving a CoP of up to 5. It has a high level of integration and despite its compact dimensions, incorporates a 200 litre domestic hot water cylinder.

The integral heat pump manager complements the advanced design and allows for easy operation with a clear, backlit display and touch wheel control.

It’s available in four capacities: 5, 7, 10 and 13kW, delivering heating outputs of 5.88, 7.61, 10.31 and 13.01kW respectively.

All four models have the same compact dimensions: H 1917 x W 600 x D 703 meaning it can be easily incorporated in a small utility room, garage or plant room.

   

WPF S

5kW, 7kW, 10kW, 13kW capacity models

Like the WPC S, the WPF range achieves the sought after CoP of up to 5, and offers powerful performance, so it can be suitable for larger buildings.

It’s extremely quiet in operation due to advanced acoustic separation.

This model does not feature an integrated domestic hot water (DHW) cylinder, but can be combined with all Stiebel Eltron DHW cylinders.

It’s available in four capacities: 5, 7, 10 and 13kW, delivering heat outputs of 5.88, 7.61, 10.31 and 13.01kW respectively.

All four models share the same compact dimensions: H 1319 x W 598 x D 658, but remember, you will need to factor in the dimensions of the DHW cylinder when planning the space the system will require.

   

WPF S basic

The WPF S basic series comes in 5 capacities and can be combined with any of the Stiebel Eltron DHW cylinders to match your demand.

It has an energy efficiency class A rating.

Available in five capacities: 5, 7, 10, 13 and 16kW, delivering heat outputs of 5.80, 7.80, 9.90, 12.59 and 16.64kW respectively.

All five models share the same compact dimensions: H 960 x W 510 x D 680, but remember, you will need to factor in the dimensions of the DHW cylinder when planning the space the system will require.

   

WPF M S/WPF Set S

The WPF M S heat pump comes in two capacities, 7 and 10kW and can be used in cascade as a set to deliver capacities of 14, 17 and 20kW, making this particularly suitable for commercial settings.

Delivering heating flow temperatures of up to 60°C, these heat pumps can work with traditional radiators so can be easily retro-fitted to an existing system.

The 7, 10, 14, 17 and 20kW models and sets deliver heating outputs of 7.80, 9.90, 15.60, 17.70 and 19.80kw respectively.

Dimensions for the 7kW model are: H 971 x W 510 x D 640. For the 10kW model they are: H 960 x W 510 x D 640. The set capacities of 14, 17 and 20kW share the following dimensions: H 971 x W 1240 x D 640, but remember, you will need to factor in the dimensions of your chosen DHW cylinder when planning the overall space the system will require.

   

WPF 20 – 66/WPF 27 HT

Specially developed for larger residential complexes and commercial or industrial buildings, these compact, cascading heat pumps can achieve a heat output of up to 400kW. To save space, each pair of heat pumps can be stacked in piggyback formation.

The system also has the potential for remote PC monitoring which is ideal in tenanted properties.

Available in 20, 27, 35, 40, 52 and 66kW capacities and a High Temperature 27kW model, these heat pumps deliver heating outputs of 21.50, 29.69, 38.04, 43.10, 55.83, 67.10 and 27.41kW respectively and are A++ energy efficiency rated.

All models have the same dimensions: H 1154 x W 1242 x D 860.

The WPF 27 HT model can achieve flow temperatures of up to 75°C, creating high levels of DHW convenience, and an integrated heat meter can calculate the amount of heating energy consumed at any time.

How does it work?

With the aid of a ground source heat pump, solar energy stored in the ground can be collected and used to heat your home or business.

The term ‘ground source’ covers four different underground heat sources: surface soil, rock, ground water and lake and the source that best suits your location is determined by factors such as the building’s heating needs, your current heating system and the kind of terrain the building stands on. Our expert assessors and installers can advise which of these is the right source for you.

Just a few feet underground, there is a fairly constant, average temperature of 4° - 12°C (usually 9° - 10°C in Yorkshire) – a vast reserve of low grade heat waiting to be tapped and harnessed to heat your home. The ground source heat pump gathers heat from this solar energy stored underground by using collectors buried in shallow trenches or in boreholes deeper underground.

The heat is transferred from the ground to a heat pump using a mixture of water and an environmentally-friendly anti-freeze solution. It circulates through a closed loop, absorbing thermal energy from the earth and carrying it to the heat pump.  

A refrigerant circulates in a second closed loop in the heat pump, though an evaporator and compressor or heat exchanger. This allows the heat from the ground to be retained and converted into high-grade heat for release into your home via water-based radiators or underfloor heating and into your hot water tank. The refrigerant then passes into a condenser before beginning the cycle once more.
