Ground Source Heat Pumps

Heating System

Cold Medium from Collectors

If grid electricity is used for the compressor and pump, then you should consult a range of energy suppliers to benefit from the lowest running costs, for example by choosing an economy 10 or economy 7 tariff.

For installations over 12kw, Ground Source Heat Pumps installed by Solo Heating Installations will require a 3-phase electrical supply. Below 12kw will only require a normal single phase supply as the NIBE units installed by Solo use soft start mechanisms.

Contrary to popular belief, Ground Source Heat Pumps installed by Solo Heating Installations run almost silently and are comparable to a fridge freezer. In new timber frame buildings built to the Building Regulations, sound transfer is almost zero.

Horizontal Loop - Ground Source Heat Pumps

These are used when you have space in your garden to lay the pipes horizontally through the ground. Trenches are dug around one metre in depth and 600mm - 900mm wide. The collector pipes are then laid into these trenches and back filled with the removed earth. Trenches must be a minimum of one metre apart and one metre from any foundations or building services. Average collector length is around 450 metres, therefore 450 square metres of area is required.

Open Loop Systems - Ground Source Heat Pumps

These are the most efficient systems and are used where a stream, underground water table or lake is next to the home. Pipes are laid onto the bed of the lake and weighed down with concrete or some other weight system. We can then extract the heat from the free flowing water that moves around the system. Special design considerations are given to avoid a flow short-circuit and flow direction must be taken into account as well. These installations do require a permit and must meet statutory requirements.

NIBE Ground Source Heat Pumps

Your energy consumption for heating will be lowered by up to 75% with the use of NIBE ground source heat pumps.

NIBE 1140 Ground Source Heat Pumps

NIBE produce 15 different types of Ground Source Heat Pumps, ranging from 5kW to 40kW. By using a cascade connection it is possible to achieve an output of 360kW.

The energy consumption for heating and hot water can be lowered by up to 75% in comparison to heating systems using fossil fuels.

NIBE FIGHTER 1140 is a ground source heat pump for heating small and large houses and industrial buildings.

NIBE FIGHTER 1140 ground source heat pumps are equipped with a control panel that offers plenty of functions.

The new features are:

- Large control panel with clear symbols
- The easily understandable controls simplify the control and operation of the heat pump
- Double heat curves
- Programmable for climate and cooling control
- Clock
- Timer for temperature control
- Timer for ground source heat pump hot water function
- Prepared for GSM- and Internet-integration
- Control unit for swimming pools
- Alarm logbook
- Choice of language
- Soft start relays
- Prepared for the configuration of four different installation systems
- Display of the ground source heat pumps refrigerant temperature

NIBE 1240 Ground Source Heat Pumps

The NIBE 1240 ground source heat pump system is suitable for small or medium sized family homes, with average demands for hot water. They come with an inbuilt hot water heating system and electric immersion heater backup. The tank in tank heating system for hot water ensures the entire 160 litre hot water tank comes to temperature in the fastest time, and by mixing the hot water down to useable temperatures through blending valves, the actual useable storage volume increases significantly.

Upgrades to 1240 Ground Source Heat Pumps

NIBE 30/40 Exhaust Air Module - Ground Source Heat Pumps

This unit is the ideal solution in new buildings to meet the energy savings directive, and renovated buildings to reduce issues with ventilation. It combines heat recovery ventilation with the 1240 unit to increase the total system efficiency and ventilate stale air areas of your home.It attach's directly on top of NIBE 1240 ground source heat pumps.

NIBE 10/20 Passive Cooling Module - Ground Source Heat Pumps

The PKM unit will allow free cooling of a property over a suitable surface area. Heat will be taken from a space through underfloor heating or fancoils to actively cool an area down in the summer. The unit can actively cool a house down whilst still providing hot water supplies through a separate heating coil.

NIBE HPAC Cooling/Heating System - Ground Source Heat Pumps

The HPAC unit will turn a NIBE 1140 / 1240 and 1330 ground source heat pump into a complete climate controlled system. Heat energy will be taken from warm rooms during the summer and transferred through the ground coils into the earths soil. This charging effect during the year increases the systems efficiency during the winter as the stored energy in the ground is taken for use. Solo Heating Installations would recommend this upgrade for large houses or large surface area rooms in conjunction with underfloor heating.

Solo Heating Installations recommend NIBE Ground Source Heat Pumps.
