MCS Heat Pumps Case Studies

Private Client – Bumpers Oast
Year:
Site:
Bumpers Oast, Kent
Description:

Bumpers Oast sits in the heart of the Kent countryside, standing proud, with a cluster of 3 classic brick-built Oast Houses. The Oast buildings are Timber Framed with smooth circular wall interior and curved bricklaying, curved walls and a detailed tiling pattern.
Internally, the central roundel is open to the roof offering a spectacular open plan interior. The 3 of the 4 bedrooms, each occupying a roundel of it’s own with a separate curved staircase to a mezzanine floor. Each bedroom has an en-suite bathroom, finished with micro-cement walls and floors.
On the ground floor, the house is largely open plan, having a polished concrete floor with Under Floor Heating throughout, installed by the Reina Group.

System Design:

We installed a 12kW Thermia Ground Source Heat Pump with 600 metres of pipe buried in the area adjacent the property. Considering the open plan and high ceilings of all three Oasts the heat pump will be able to provide enough constant heat and a constant supply hot water.

Reina Group Scope of Works:

This was a spectacular project for The Reina Group. Having visited the property in the early stages of the build, we recommended a Ground Source heat pump primarily because the property sat on plenty of flat land, perfect for laying horizontal loops which are buried in the garden. The heat from the ground is absorbed into the fluid in the loops, which is then passed through a compressor that raises it to a higher temperature and as a result water is heated ready to be distributed around the property for heating and hot water.

Site:
Aldington, Kent, Nr Ashford,
Description:

A stunning property in Aldington, Kent having been occupied by the same owner for over 60 years. The interior of the 34 roomed Georgian house was like a scene out of Pride & Prejudice with many of the original features still apparent.
The original heating system was a combined Trianco air source heat pump connected to oil central heating. Due to the size of the property and inefficiency of the old heat pump, the current heating system did not work effectively and with oil prices inflating yearly, heating costs were expensive reaching over £3600 per annum.

System Design:

Our initial recommendations were to install a Ground Source Heat pump, as the house had a large field at the back of the house, perfect to accommodate the underground looped pipes, although on closer examination having to run through an orchard. It was also suggested that larger radiators were installed in each room to improve the heat output, irrespective of heat source.
After further discussions and recommendations took place it was agreed to install a Nibe ASHP using the oil heating as a backup, when outside temperatures drop below 7 degrees. The client was keen to keep the original radiators to experiment and see if the Nibe ASHP worked effectively, using only the oil boiler as a backup, in cases of extreme cold weather. So far, the oil boiler has not been used, however mild weather may have influenced this. The client expects that the true test will come, during the extreme weather conditions.

Reina Group Scope of Works:

Installation was smooth and fluid leaving our customer with a satisfied impression of the Reina Group. He praised the experienced and professional workmanship of our Heat Pump Engineer. “The complete installation process was slick and well-done, I was particularly impressed by the removal of the old water tank and HP, which was successfully recycled, locally”.
In the first quarter the client's experience is encouraging with the economical view that his hot water and heating has cost in the region of £450 with no oil being used. The HP has consumed 3033 kWhrs and produced 9548 kWhr which provides a staggering 3/1 plus output.
The client has also applied for The Renewable Heat Incentive (RHI) which is a Government initiative offering a tariff payment each year, for a set period.
The RHI will be paid to the client and calculated at a set rate per unit of renewable heat produced (kWh) for seven years. For air source heat pumps (ASHP) the rate tariff was 10.49p /kWhr but has subsequently increased to 10.71p
On reflection the client could not speak more highly of his experience with the Reina Group “The Reina Group appear to be courteous but cautious”. His only criticism being the RHI paperwork was a little difficult to understand and was rather lengthy. The Reina Group ensured that help was available, and all paperwork submitted was correct.

The heating distribution method, combined modern under floor heating to the ground floor with a traditional radiator system to all upper floors. All the bathrooms were fitted with a towel rail, with a separate heating circuit, enabling a higher temperature for towel warming. Hot water was provided via a 200 litre unvented cylinder.

Site:
Postling, Nr Folkestone, Kent CT21
Description:

A 400m2, three storey state of the art dwelling, built to modern methods of construction, which included an indoor heated pool.

System Design:

The main part of the dwelling is fitted with a Nibe Fighter 1330 22kW ground source heat pump, which draws energy via a 6 x 100m bore-hole matrix.

The energy sourced from the ground is stored within a 200 litre buffer vessel for heating distribution, within a under floor heating system, set in the floor screed to the ground and first floor. The second floor benefits from an Uponor Unipipe system 12 (15mm floating floor panels combining a 12mm pipe due to height restrictions). The hot water is provided via a 500 litre VPAS cylinder linked to solar collectors.

A Mechanical Ventilation with Heat Recovery (MVHR) system was installed throughout, which complemented the designed low air permeability of the building. The MVHR system incorporated comfort cooling to all bedrooms, which utilised an existing ducting system.

The Swimming Pool is heated continually by an additional Nibe Fighter 22kW ground source heat pump, which draws energy from 6 x100 meter bore holes. This energy is then distributed to a 200litre buffer.

Bilsington, Nr Ashford, Kent TN25
Description:

Renovated pre 1900’s building incorporating a new build extension. The four bedroom property consisted of an en suite and two bathrooms.

System Design:

A Nibe Fighter 1145-12 Ground Source Heat Pump (GSHP) has been installed which extracts energy from the ground via 2x 81meter vertical ground collectors (borehole). The heat produced from the GSHP is distributed via a 200litre buffer vessel. This is connected to an underfloor heating system, supplying heat to the new extension in the home and designer low temperature radiators to the original building. It also heats a 300litre unvented hot water cylinder which incorporates a secondary hot water pump allowing instant hot water at the hot tap in the building.
The plant room is located in the garage which is situated away from the main building and is connected via uponor ecoflex which is a flexible, pre-insulated piping system. This allows for minimal heat loss from the plant room to the home.

Great company - I needed a complete fit out for a very large new build. I didn't want to use a heating company that were too large and 'corporate' as the price can get out of control but with Reina Group Ltd I found they had all the skills and experience in house to do a high-quality job. Very neat, and they use specialist materials for a better installation which I feel I can rely on. They also helped me with some second fix work and I understand my principal builder (highly experienced) has now asked them to take on their next new build project. Honestly - Reina Group Ltd were excellent!
