Offsite building provider installs new eco-building at premium holiday resort in Kent, utilizing the ESP Ecocent MEV.

Oxfordshire based Green Unit installs their ARC™ eco-building at environmentally-conscious, self-catering holiday resort, Great Field Farm near Canterbury. The premium eco-building, known as the Green Unit ARC™, was manufactured offsite in modular sections and delivered to the Great Field Farm site virtually complete.

The building’s unique curved design mimics the natural environment, and the use of sustainable materials creates a calm and relaxing getaway for holiday goers in the heart of the Kent Downs. It's positioned on a prime spot overlooking green vistas; well placed to benefit from stunning sunsets and the night’s sky. 

The 90 sqm building is equipped with environmentally-friendly features such as a green roof, a heat exchange system, infra-red underfloor heating, and smart sensors to regulate pollen, CO₂ levels, ventilation, heating and lighting. The Ecocent Ambient MEV which is installed in the ARC™ is a combined heat pump and unvented water cylinder. This heat pump can draw air internally or externally and is equipped with the latest EC fan motor. The tank is constructed from Duplex SS-2205. ESP Ecocent units are industry leading, innovative hot water supply systems which use a built-in Air Source Heat Pump to scavenge waste heat and make domestic hot water production highly efficient offering a saving of up 70%.

The building’s three bedrooms comfortably sleep six people, and it boasts a westerly facing glazed end where guests can enjoy stunning sunsets within the state-of-the-art kitchen and a beautiful living space.

Mr and Mrs Castle, the owner-managers of Great Field Farm, are looking forward to welcoming guests into their ARC™ - fondly named the Bumble Barn - at the end of May. The new accommodation offers Mr and Mrs Castle a unique opportunity to expand their environmentally-conscious business, allowing the couple to cater to the demand for larger families and groups. 

Lewana Castle said that she and her husband “just fell in love with the concept and design of the ARC™ as soon as they saw it.

“We chose the Green Unit ARC as we liked the idea that it can be built under cover in the winter, is delivered practically complete, and that disruption on our site is minimal, so not affecting our other holiday guests."

We pride our business on offering guests the space and freedom of the outdoors, but with the warmth and comfort of a house, and the new ARC building offers exactly that. Our guests will love the new experience of living in the round of the curved building, and I think they’ll be interested in the ARC’s sustainable features and clever technology. We’re looking forward to welcoming guests into our new ARC accommodation, and we’re sure that it’s an excellent investment for our business.

Jonathan Finnerty, Managing Director of Green Unit, said “the Great Field Farm project marks an important milestone for Green Unit as we deliver the ARC into what we expect to be the first of many businesses within the UK tourism sector.”

Achieve Improved SAP & EPC Ratings for your property with an Ecocent MEV System

Achieve Improved SAP & EPC Ratings for your property with an Ecocent MEV System

Paul Mansell

23 Sep 2019

Ecocent Hot Water Cylinder/MEV System achieves a higher SAP score than a conventional Mechanical Extraction Ventilation with electric water tank.

The Ecocent has now been tested for MEV as well as a heat recovery heat pump for DHW. The Ecocent compressor only runs when it's producing DHW; at all other times it's in fan mode only like a standard MEV unit. The difference between a standard MEV and the Ecocent MEV is that the Ecocent makes hot water from the air that gets expelled by means of a heat pump built into the Ecocent. The standard MEV just drags in fresh air and expels the spent air.

The Ecocent will enhance the SAP calculation process, which will improve the overall EPC rating of your property. The Ecocent delivers a reliable supply of hot water, improved air quality and essential ventilation for all wet rooms within the property. This is achieved by combining the Ecocent’s air source heat pump (ASHP) and it’s MEV system.

The Earth Save Products Ecocent can be used as a combined hot water heat pump and MEV giving a higher SAP pass.

It isn’t just a combination of a mains pressure hot water cylinder and MEV fan; it’s the only unit of its type which is in the SAP data base. The Ecocent also has a built in Micro High Temp Air Source Heat Pump combined with a built in MEV ventilation Fan System which means that whenever the unit is in hot water production mode, the waste heat/air which would normally be lost to the outside via the MEV part of the system has the heat/energy extracted from it, up-scaled in temperature and recovered into the hot water via the built-in ASHP.

This means the Ecocent, depending on air flow rates, can potentially achieve an efficiency of up to 400%.

The Ecocent has been extensively tested by BRE and subsequently entered into the SAP data base. In fact, it’s the only hot water production and ventilation system of its type in the PCDB/SAP listing. The upshot of the testing and SAP listing means that if the Ecocent is entered into the SAP calculations of a new proposed dwelling, then in many cases this renewable technology may be the only one needed to achieve a SAP pass. If combined with a Bioethanol Stove (which can cost as little as £69) it can increase the pass mark even further. However, if you entered an alternative tank and MEV fan, for example separately, you wouldn’t achieve any significant uplift in the result.

The Ecocent system is simply demonstrated in a video. Go to 'Videos' on our profile.

Ground Source Heat Pumps Explained

Ground Source Heat Pumps Explained

Paul Mansell

23 Sep 2019

Earth Save Products have Heliotherm GSHPs amongst their range of renewable energy products.

Ground source heat pumps (GSHPs) absorb heat from under the ground and use it to heat domestic or commercial premises via radiators and/or under floor heating systems. Systems use the heat pump and a compressor to remove heat from one side of the circuit and eject heat to the other side. A geothermal heat pump moves heat into or out of the earth using either water wells or a network of high-density polyethylene pipes buried in vertical boreholes.

The pipes carry a water and antifreeze solution, which is pumped through the pipes buried in the ground. The heat transfer fluid extracts heat (heating mode) from the earth surrounding the ground loop system. The geothermal heat pump increases the heat, which is then distributed throughout the building by the chosen heating system. The heat pump also has the capacity to work in reverse and provide a cooling system (heat pump dependant).

The primary fuel for a ground source heat pump is heat from the earth which is freely available. Depending on which fuel you are replacing the carbon emission savings can be as high as 3.6 to 10.5 tonnes per year. You’ll no longer need fuel deliveries to your home and will be contributing to the UK 2020 target for reduction in carbon emissions.

A Geothermal heat pump’s main components are:

·        The Evaporator (e.g. The squiggly thing in the cold part of your fridge) takes the heat from the water in the ground loop.

·        The Compressor (This is what makes the noise in a fridge) moves the refrigerant round the heat pump and compresses the gaseous refrigerant to the temperature needed for the heat distribution circuit.

·        The Condenser (The hot part at the back of your fridge) gives up heat to a hot water tank that feeds the distribution system.

What advantages do geothermal heat pump systems offer?

·        A 25 to 40 percent reduction in heating and cooling costs

·        Standard, simple controls

·        No need for a highly specialized chiller technician or boiler operator

·        Highly durable piping (the life expectancy is between 30 and 50 years)

·        No high-maintenance, freezing-prone cooling tower

·        No boiler to clean or maintain

·        No air conditioning equipment on roof to cause leaks

·        No harmful chemicals

·        No danger of fire, asphyxiation, or explosion from coal, gas, or oil

·        Nothing outside to vandalize or steal

·        No central system to fail or shut down the entire building

Boreholes and Ground Source Heating Principles

Underneath the frost line, the ground stays at a constant temperature of about 57 degrees Fahrenheit. That happens to be an extremely efficient operating temperature for heat pumps. Geothermal heat pump systems circulate water between an underground water loop, called an earth heat exchanger, and water-to-air heat pumps located throughout a large building. There are little or no disadvantages with Geothermal Heat Pump Systems.

What to keep in mind when considering a ground source heat pump:

·        The type of heat distribution system. GSHPs can be combined with radiators but under-floor heating is better as it works at a lower temperature.

·        Is there space to get the rig in to install the ground loop?

·       What fuel is being replaced? If it’s electricity, oil, LPG or any other conventional fossil fuel the payback will be more favourable. Heat pumps are a good option where gas is unavailable.

·        Is there also a cooling requirement?

·        Is the system for a new building development? Combining the installation with other building works can reduce costs.

·        Can you incorporate insulation measures? Wall, floor and loft insulation will lower your heat demand.

·       Low Maintenance; a ground source heat pump is a ‘fit and forget’ technology which doesn’t require you to interact with it in any way once you’ve had your handover at the end of installation.

Easy to Manage

Engineers will conduct a handover session with you to thoroughly familiarise you with the new system and will be at the end of the phone or attend in person should you have any queries.

Earn money

Installing a ground source heat pump means you could qualify for RHI payments.

Is an air source heat pump right for you?

Is an air source heat pump right for you?

Paul Mansell

23 Sep 2019

Air source heat pumps absorb heat from the outside air. This heat can then be used to heat radiators, underfloor heating systems, or warm air convectors and hot water in your home. An air source heat pump extracts heat from the outside air in the same way that a fridge extracts heat from its inside. It can get heat from the air even when the temperature is as low as -15° C. Heat pumps have some impact on the environment as they need electricity to run, but the heat they extract from the ground, air, or water is constantly being renewed naturally.

The benefits of air source heat pumps

Lower fuel bills, especially if you are replacing conventional electric heating

potential income through the UK government’s Renewable Heat Incentive (RHI)

lower home carbon emissions, depending on which fuel you are replacing

no fuel deliveries needed

can heat your home as well as your water

minimal maintenance required

can be easier to install than a ground source heat pump.

Unlike gas and oil boilers, heat pumps deliver heat at lower temperatures over much longer periods.

How do air source heat pumps work?

Heat from the air is absorbed at low temperature into a fluid. This fluid then passes through a compressor where its temperature is increased, and transfers its higher temperature heat to the heating and hot water circuits of the house. There are two main types of air source heat pump systems:

An air-to-water system distributes heat via your wet central heating system. Heat pumps work much more efficiently at a lower temperature than a standard boiler system would. This makes them more suitable for underfloor heating systems or larger radiators, which give out heat at lower temperatures over longer periods of time.

Air-to-air

An air-to-air system produces warm air which is circulated by fans to heat your home. They are unlikely to provide you with hot water as well.

Is an air source heat pump suitable for me?

To tell if an air source heat pump is right for you, there are a few key questions to consider:

Do you have somewhere to put it? You'll need a place outside your home where a unit can be fitted to a wall or placed on the ground. It will need sufficient space around it to get a good flow of air. A sunny wall is ideal.

Is your home well insulated? Since air source heat pumps work best when producing heat at a lower temperature than traditional boilers, it's essential that your home is well insulated and draught-proofed for the heating system to be most efficient.

What fuel will you be replacing? The system will pay for itself much more quickly if it's replacing an electricity or coal heating system. Heat pumps may not be the best option for homes using mains gas, but for anyone who is ‘off grid’ they are ideal.

What type of heating system will you use? Air source heat pumps can perform better with underfloor heating systems or warm air heating than with radiator-based systems because of the lower water temperatures required.

Is the system intended for a new development? Combining the installation with other building work can reduce the cost of installing the system.

Using Air-Source and Ground-Source Heat Pumps with Underfloor Heating

Using Air-Source and Ground-Source Heat Pumps with Underfloor Heating

Paul Mansell

23 Sep 2019

Both Air Source and Ground Source heat pumps complement Underfloor Heating (UFH) perfectly, although there are some factors that always need to be considered.

The reason that UFH works well with heat pumps and is more efficient is because it requires a much lower flow temperature than traditional heating systems. Radiator heating systems work on a boiler flow temperature of 70-80 degrees, but UFH only requires in the region of 30-50 degrees, which is the typical range of flow temperature that a heat pump will provide.

The Design Process

ESP offer a comprehensive design service, taking into account the specific requirements of our own range of heat pumps. It’s important that any specified parameters are incorporated into any UFH design.

There are several input parameters that will define the design of your UFH system:

The fabric heat loss of the building to be heated

The manifold location

The size of the UFH pipework installed

The spacing between each run of pipework installed

The flow temperature provided by the heat source

The room design temperature (the target temperature you are trying to achieve)

The proposed floor coverings in each area

The external weather conditions

The type of UFH system to be installed will be determined by the floor construction in the area to be heated. UFH systems for different floor constructions will vary in their heat output capability, which is all taken into account in the design process.

The most efficient way to assess whether or not the UFH will adequately heat any room is to work back from the heat loss at ‘worst-case scenario’ external weather conditions. Room-by-room heat loss calculations can subsequently be compared to the heating output to make sure that the UFH is providing adequate heating to each specific area.

How Does A UFH System Differ When Used with A Heat Pump?

A UFH system installed utilising a heat pump will be made up of exactly the same components, the main difference being that as the water will be supplied directly to the manifold at a relatively low temperature, there won’t be an additional need to mix the water at the manifold stage, removing the need for a local blending valve.

Hi Guys, Just a quick note to thank you all for your patience and understanding while we made up our minds whether or not to purchase your system. All my questions were answered in a way that even I could understand. It was a very heartening experience to deal with a company that has an interest in really caring about their customers as you all seem too. In our quest to reduce our energy costs we spoke to many people, nearly all of whom did not bother to get back to us. I spent years in customer service fighting to get the motor trade to take care of their customers, but many would not be near your standards. Many thanks again to all of you for all your help, I am sure that your attitude will ensure your business thrives. We will certainly do all we can to recommend you. Kind Regards, Martyn.

Nick... good morning. Now our building project is virtually finished and Jenny and I have finally moved in, we would like to record our praise and thanks for the help, advice, and after-sales service we have received from you and the ESP team. This started with us being complete novices wrestling with the initial mine-field of trying to ascertain the best and most cost-effective ‘green’ system of providing heating and domestic hot water, and ending with the system you recommended working efficiently. Consultation with several local ‘expert’ suppliers had done nothing to clarify our initial confusion, and in several cases caused sleepless nights due to incredible quoted system costs……. We are grateful therefore to The National Self Build & Renovation Centre for recommending ESP as a straightforward, no-nonsense supplier/adviser. Following our visit to your works we left feeling clear in our minds as to the best way forward. We have already, and will continue, to recommend your services to anyone we meet who are looking to embark upon a similar journey to ours. Thanks again Simon.

Swimming Pool Heat Pump

Swimming Pool Heat Pump

Hi Nick, You sold me a heat pump for my place in France in April which I am really pleased with. I have installed it with an energy monitor so I can track the costs; currently it is averaging out at €3.50 per day, which when you consider the awful weather we have had I consider this to be really good. The pool is set at 26 degrees which is higher than I would have had it with the oil boiler. In the past we have used 1800 to 2000 litres per year which this year would have cost us in the region of €1800 for the year. Even if this terrible weather continues, with the heat pump the annual running cost (based on a 4 month swimming season) should be just over €400. I just thought you may be interested in a real life figures. I really think there may be a chance to start fitting these as a business out here. The local pool shops are fitting 9kw pumps that are just not powerful enough to heat the pools here and I think this could be a viable business opportunity. Let me know what you think. Many thanks Rob & Trudy Bonne Chere

Great independent advice. Our family home is an old oil-heated property that we extended & improved over a period of 30 years. We decided to install a whole house MVHR system which also recycles air to the Earth Save Products Ecocent DHW heat pump for cost effective DHW generation. Following sound advice from ESP, we also opted to install two separate heat pumps – one to heat the hot water & another for the space heating. DHW & Heating require different levels of heat & energy so it was more economical in the long run to fit two independent systems that were well suited to their specific tasks. Since we completed, we’ve had quite a few people come & look at what we’ve installed & a number have decided to adopt the same system for their own new builds. I would advise you do your research and seek sound non-sales-orientated advice when it comes to your choice of technology. Our equipment provider ESP did just that & the design, recommendations and cost have all lived up to our expectations.
