MCS Heat Pumps Case Studies


Client:
Private Client – Lymbridge Green Farm
Year:
Site:
Lymbridge Green Farm - Stowting, Kent
Description:

Lymbridge Green Farm is a stunning 400 year old farm house located in a quaint Kent village. The house comprises of 4 big bedrooms and 5 reception rooms downstairs all with the original features; low ceilings, beams and an impressive open inglenook fireplace in the lounge.
A log burner in the kitchen was the main source of heat along with an Arga which heated the kitchen, leaving the other reception and bedrooms chilly during the winter months. The homeowner was consistently having to feed the burner with wood which consisted of several trips to the log store a day and a consistent supply of logs, just to keep the house heated. The owner said “so much time evolved around the logs and keeping the house warm”!
The homeowners when looking at a new heating system did not consider renewable heat pumps as a solution as they did not believe such an old property would fit into the criteria. Knowing of the Reina Group they enquired about different economic heating systems for homes that were off gas. They were surprised when an Air Source heat pump was recommended as the most economic heating solution and with the money back RHI scheme, their decision was made for them.

System Design:

The new heating system was carefully designed and installed to ensure that the character of the cottage was not affected. It was agreed to install a couple of new radiators into the bedrooms to increase maximum efficiency. We chose a Nibe F0240 ASHP which was perfect for this type of house. The pump was located under the study window at the rear of the property, being the most inconspicuous place, with the control panel hidden in a small cupboard in the dining room with easy access. Installation was quick and seamless with little disruption during the time our engineers were on site.

Reina Group Scope of Works:

The client has now had the heat pump for 4 months and is amazed with the results. Since the heat pump was installed the whole house is kept to a nice comfortable temperature of 21° throughout the day. All the rooms in the house are the same temperature which is a novelty for the owner. The heat pump operates the heating and hot water which is a luxury for our client having had limited hot water and inconsistent heating throughout. “Having a heat pump has been an absolute life changer” commented the client. The many hours filling up the wood burner to keep the house warm are no-longer required which creates more free time

Client:
Private Client – Ocean Mist
Year:
Site:
Ocean Mist, Hythe, Kent
Description:

Visiting Ocean Mist was an absolute delight, a modern 5 bedroomed family detached modern house built 10 years ago, maintained and groomed to a very high standard.
With an existing gas boiler not working efficiently and ongoing issues with water pressure from a tank fed system the client started looking into a renewable heating solution, with a vision for a more contemporary, environmentally friendly method of heating his home.
The house already has PV Solar panels to help supplement the hot water which our client had invested in previously, and so far, had experienced a positive feedback. He was keen to look at renewable heating having had a background of dealing with eco-friendly products and reading about the future of sustainable influences and products in the market.
His website research led him to the Reina Group, being a local design & installation company with a proven track record in both air & ground source Heat Pumps. His first impression with the Reina Group was a positive one with a meeting arranged on the same day of his first enquiry. The client already had a little understanding of heat pumps but was encouraged about the Reina Group’s in-depth knowledge and experience of heat pumps. “It was all about finding the right system and the right company who were offering a competitive price” commented the client.

System Design:

Our engineers arrived on site in August and with very little disruption, took out the existing boiler before installing the new Nibe F2040 12kW Heat Pump, taking only a week from start to finish. The client remarked that it was a seamless operation and how courteous, tidy and professional our engineers were throughout the installation.
The heat pump unit is fixed onto the rear wall of the property and does not ruin the aesthetic image of the maintained patio and garden area. There was a soft hum coming from the unit which was no noisier than a fridge which cannot be heard if you were sitting out in the garden area. The SMO 20 control panel for the Nibe heat pump was housed in a small downstairs cupboard, neatly installed, together with all the house, alarm controls & electrical circuit boards. The large cylinder is accommodated into a narrow cupboard in one of the bedrooms, completely out of sight and not impacting on any of the living space.
The Solar PV array was left connected to supplement the HW demand through an Immersun solar power diverter, heating the water through the cylinder’s immersion.

Reina Group Scope of Works:

Since the installation of the heat pump the house is kept to a nice comfortable temperature of 21° throughout the day. The house boasts a large open plan kitchen/living area, with a large lounge off the entrance hall, with heat generated from the underfloor heating.
Upstairs is kept at a perfect temperature with radiators in all bedrooms. The client is now reaping the benefits of living in an energy efficient home and getting used to this lifestyle change, living with a comfortable temperature all the time instead of surges of heat twice daily, when the heating came
on, with his old system. In addition the client installed an electric towel rail in the bathroom upstairs to dry damp towels which is a great solution for this purpose.
The client has calculated his usage of electricity with the new Heat Pump system, with his initial findings from Sept – Oct using only £5.30 of electricity daily for the whole house. He estimates a figure of £1600 a year, a huge saving from his existing utility bills.
The client is taking full advantage of the RHI, government incentive scheme available to homeowners installing renewable energy heating systems. An online application whereby our team guides the client through, to ensure clarity and completion without any stress.
The client estimates that on the figures he has collected so far, he expects to have recovered his initial installation costs within 6 years.

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.

Private Client – Symnalls
Year:
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.

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!
