Bespoke Designed & Built Buffer Tanks

buffers diagrams 1Earth Save Products are now able to offer designed/custom built buffer tanks for any project from small residential to large heating and cooling projects, including biomass projects, district heating, CHP (Combined Heat & Power) systems and chilled water systems. For those not in the know, a buffer tank retains heat for later use and can supplement the heat source when demand is high or store heat when demand is less. Stored heat can be immediately accessed without the heat source needing to get up to temperature; this is very useful for maintaining a constant output. Contact us on 01865 598158 for more information.

The Ecocent MEV System Simply Explained

The Ecocent MEV System Simply Explained

If you'd like more information about our innovative Ecocent MEV System, 'Request A Call Back' and we'll get in touch with you as soon as possible.

The Ecocent MEV-EAHP Hot Water and Ventilation System is a unique product that has been tested and approved by the Building Research Establishment for inclusion in the Government Approved SAP Software (PCDB Listing)  which is the mandatory system used to calculate property SAP Ratings and Energy Performance Certificates (EPCS). In recent years, developers have often resorted to installing PV and Solar Hot Water Panels to achieve compliant SAP ratings on new build properties. The ECOCENT MEV-EAHP can help achieve a compliant SAP RATING without the need for either of these systems, which often upset the cosmetics of the property exterior and which rely on a suitable property orientation.

The use of an Ecocent MEV-EAHP Hot Water and Ventilation System will help new build properties achieve compliance of both Part L and F of the Building Regulations, but its use is not limited to new build properties. It is a system that can easily be incorporated in most properties new or old and can dramatically improve energy efficiency and the living environment.

Modular Eco Building company choose Ecocent MEV system

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.

green unit 1

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. 

green unit 3

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%.

green unit 5

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.

green unit building

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. 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.”

Sales of the Heliotherm range of Air Source & Ground Source Heat Pumps Soar

HeliothermWe’re pleased to announce that UK sales of the Heliotherm range of air source & ground source heat pumps has exceeded all expectations. Not that we were in any doubt that once we demonstrated the capabilities of these high quality units to deliver maximum performance with minimal effort for renewable cost effective energy that there wouldn’t be a huge demand. The uptake has been impressive, from self-builders and developers alike, with interest shown from one local authority whose environment officer visited our showroom to check out the noise level.

“OK. You can switch it on now…” she said. I think the appropriate phrase to describe her reaction when we told her it was already on is ‘gobsmacked’.

A leading air source heat pump manufacturer is currently ‘shouting’ about their ultra-quiet 8.5 kW unit with a quoted sound output of 58db(A). Our Heliotherm 8kW has an even lower output at 29.4db(A).

Do You Need Blockchain?

Blockchain technology is a hot new trend, with almost 60% of the world’s largest companies now considering it as a way to improve the security of their data. What is Blockchain?

By allowing digital information to be distributed but not copied, blockchain technology created the backbone of a new type of internet. Originally devised for the digital currencyBitcoin, the tech community is now finding other potential uses for the technology.

Bitcoin has been called “digital gold,” and for a good reason. To date, the total value of the currency is close to $9 billion US. And blockchains can make other types of digital value. Like the internet (or your car), you don’t need to know how the blockchain works to use it.

Blockchain Technology

Relational databases are today’s gold standard. They depend on a few trusted entities to store and update entries in tables—and to control the data’s security. Blockchain technology changes the way data is managed. Blockchains are replicated across a peer-to-peer network, making their data hard to corrupt. They don’t rely on trusted entities. Instead, strangers work together to store, curate, and secure a growing data set.

Public Blockchains

Public blockchains typically work well because the miners, who add new data to the blockchain, are paid (for example Bitcoin and Ethereum). Public blockchains are excellent if you want to avoid censorship and provide universal access. However, they are slower and less private than databases. The costs to import data are unpredictable. So is the software, because no one entity updates it.

ESP Ecocent SAP Recommended Input Guide

SAP Input Instructions for entering hot water from an Ecocent Cylinder and MEV

Because of the number of enquiries we get about using the Ecocent as an MEV system in SAP software, we have devised this guide using the PCDB database numbers and highlight the various sections into which they must be entered: (Elmhurst ref)

PCDB Database numbers:

  • 200L Ecocent 190001, MEV 500487
  • 300L Ecocent 190002, MEV 500488
  • Maxi Ecocent 190003, MEV 500489

Section 19 (MEV) – Specify MEV – Centralised, MV reference number as above serving the relevant number of wet rooms.

Section 25 (Main Heating 2) – Specify reference as above (190001 etc as appropriate).

Section 28 (Water Heating) – Specify from Main Heating 2

This should allow the correct entry of the Ecocent as an MEV/EAHP System.

Award Winning Ecocent in Award Winning Houses

The Tigh Grian development was completed in August 2017. These social homes were designed and manufactured off site using a new method of construction said to speed up the whole build process by 25%. The homes conform to The Scottish Building Standards Sustainability Gold Level; the package that ESP delivered could not be equalled by any other supplier. They all have an Ecocent Hot Water System installed.

This new housing development for Link Group Ltd and Paragon Housing Association at Queen Street, Alva has now been officially opened by the Minister for Local Government and Housing, Kevin Stewart. The £5.3 million construction of 48 homes for social rent began in February 2016, and was supported by a grant of £3,076,916 from the Scottish Government’s Greener Homes Initiative scheme.

The Ecocent can potentially achieve an efficiency of up to 400%.

EcocentThe Ecocent 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%.
