Earth Save Products Award Winning Ecocent Hot Water System


The Ecocent unit contains Earth Save Product’s advanced heat exchange technology to recover heat from used air extracted from warm humid locations within a building. It’s designed to recover heat and moisture from what would normally be extracted (e.g. through an extraction fan to the outside). This is then used in combination with their industry leading heat exchangers to produce a reliable supply of hot water. Waste heat and unwanted moisture can be extracted from bathrooms, kitchens, vaulted ceilings and areas of excessive solar gain. Using as little as 640w/hr of electricity during operation the Ecocent unit produces an abundance of hot water at 60°C;  much less electricity than a standard kettle would use to provide a few drinks.

The electricity used by the Ecocent unit powers the integrated air source heat pump (ASHP). The unit uses smart technology to switch on and off as required, so it only runs when re-heating the cylinder after hot water has been drawn off.

The Ecocent isn’t just a combination of a mains pressure hot water cylinder and MEV ventilation. 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 (Building Research Establishment) 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 proposed new dwelling, then in many cases this renewable technology may be the only one needed to achieve a SAP pass. However, if you entered an alternative tank and MEV fan separately, for example, you wouldn’t achieve any significant uplift in the result.

Coming soon. The Next Generation Ecocent.






New for 2018 is our ESP Ecocent Ambient air source heat pump. This model intakes external air to use with it’s micro high temperature ASHP to produce hot water highly efficiently whilst maintaining the air tightness of the building.



Our Ecocent MVHR Heating and Cooling Unit meets the Hexpod House Prototype

ESP are proud to be working with Hexpod providing our Ecocent MVHR combined heating & cooling system with horizontal indirect water tank for their innovative pre-fabricated building solution. The ESP Ecocent MVHR system was recently installed into the Hexpod House. The Hexpod concept consists of a range of highly versatile, standardised pre-fabricated panels made from high strength architectural precast concrete. This innovative design enables a modern building solution suitable for both residential and commercial purposes which can be rapidly deployed and constructed.



The Most Phenomenal Heat Pump on The Market. The ESP Heliotherm.

Earth Save Products are the official UK distributor of the new ESP Heliotherm range of Air to Water Heat Pumps. This innovative series is designed for outdoor installation and can be used in multi-family homes and commercial properties. It is also the first worldwide solar supported heat pump. The ESP Heliotherm CC PV-COP-Booster Range provides the heating from 3 to 24 kW for highest heating and living comfort. The solar panel capabilities allow you to use energy as efficiently and cost effectively as possible. They are the only unit that can be directly fed from PV (via built-in invertor) and will always use this energy first before drawing from the grid. They can be monitored remotely by the manufacturer and constantly ‘tweaked’ to optimize performance. These units were designed for space heating and hot water production for both domestic and commercial buildings. End users wishing to purchase the ESP Heliotherm Air to Water Heat Pump may be eligible for maximum support through the Renewable Heat Incentive Scheme due to its high SCOP of up to 5.8.


The ESP Heliotherm Booster Heat Pump provides a significant efficiency increase for DHW and heating. It also provides a unique space saving combination of photovoltaic & full modulating heat pump. We are also proud to say that this unit is the quietest air to water heat pump on the market with the lowest operating costs and cost efficient installation.






The Heliotherm Split Unit – In A Class of Its Own

The main driving force of the design of the Heliotherm range is to produce a market leading heat pump that has the highest efficiency and performance on the market. This is clearly illustrated by the testing data pictured here and speaks for itself. The Heliotherm range of heat pumps have been designed to work in countries that have far colder climates than we experience in the UK. This is also the reason why these units are market leading in reliability. Put simply, if you had a heating issue in the Austrian mountains you would have a serious problem and it just wouldn’t be acceptable. This is precisely the area where the Heliotherm is designed, manufactured and produced to cope with this kind of environment. It’s also important to point out that the average winter temperature in the UK is 7 degrees and the heat pump design is mainly designed around that temperature whereas the starting temperature in Austria is -7 degrees. This highlights the difference between the standard UK heat pumps and the high performance of the Heliotherm range that we are offering

ESP director Dave Clarke says: “Innovation and excellence is at the heart of everything we do. That’s why we’re proud that our Ecocent has been recognised once again as a leader in efficient Renewable Energy Systems and that we have been selected to distribute the excellent range of Heliotherm Heat Pumps.”
