Heat recovery ventilation can be a mine field when it comes to selection. We want to make the best choices and select MVHR units that recover the most amount of heat while using the smallest amount of energy and give us the flexibility of air movement control we need.
We have selected the very best heat recovery units from our global range that are specifically suited to cater for the higher levels of humidity we have in the UK along with the challanging seasonal changes that cause condensation problems.
When building a house, you think about what exactly needs to be present so that you can feel comfortable in it. The indoor climate and thus the air quality play a decisive role, but one is often not aware of them as factors.
That’s a good thing, because ventilation should feel natural in living and not require a lot of attention. If you plan in the right ventilation system right from the start, you can achieve just that. In a new building, a so-called central ventilation system is very well suited because it is installed in the basement, roof or an adjoining room and is therefore practically invisible later.
A central ventilation system consists of a single device that is connected to the outside via exhaust and supply air pipes. Fresh outside air is sucked in through one pipe, filtered and fed into the various rooms via a pipe system. At the same time, the stale air is led out of the rooms via a second pipe system. In the system, the two air flows are crossed past each other in a heat exchanger, so that in the cold season the heat from the exhaust air is transferred to the cold supply air. Here, however, the air flows are completely separated from one another, so that the fresh and stale air do not mix with one another, but only the heat is transferred.
ARGUMENTS FOR CENTRALISED VENTILATION:
- Low-noise living space ventilation through an isolated system
- Lower heating costs thanks to a high degree of heat recovery
- No thermal insulation of the supply and exhaust air pipes necessary, as the air temperature in the ventilation pipe is similar to the ambient temperature.
- Optimal flow through the residential unit
- Devices with a bypass of the heat exchanger for summer days – cooling the building at night when outside temperatures are lower
- No sound transmission from room to room
- Efficient air purification through built-in supply and exhaust air filters
- Prevention of mold thanks to devices with an integrated moisture sensor
- Comfortable operation via touch control panels and mobile device with a suitable app
- Plug-and-play packages to match the number of rooms

HOW THE DIFFERENT HEAT EXCHANGERS WORK
PRINCIPLE OF A ROTARY HEAT EXCHANGER:
The rotary heat exchanger in some central systems ensures alternating warm air flow from one direction into the building and cold air flow from the other direction outside.
PRINCIPLE OF A COUNTERFLOW HEAT EXCHANGER:
The air currents move in separate channels in opposite directions through the heat exchanger. The heat from the exhaust air is transferred so efficiently to the supply air that the temperature difference between the exhaust and outside air is almost zero. Heat recovery rates of over 90% can be achieved.

Watercycles Shower Heat Exchanger
The water cycle reduces greenhouse gas (GHG) emissions without compromising lifestyle.
The water cycle is 100% recyclable.
How it works
Water drain heat recovery technology works well with all types of water heaters, especially demand and solar water heaters. Waste water heat exchangers can recover heat from hot water used in showers, bathtubs, sinks, dishwashers and washing machines. As a rule, they can store the recovered heat for later use. You will need a storage unit that can be used with a dishwasher or washing machine. Without a storage tank, you will only have usable energy when cold water and heated wastewater flow simultaneously, like when taking a shower.
Some storage systems have tanks containing a clean water tank. Drain water flows through the spiral tube at the bottom of the heat storage tank. This heats the water in the tank, which rises. Water entering the water heater is preheated by circulation through a coil at the top of the tank.
Non-storage systems typically use a copper heat exchanger that replaces the vertical section of the main sewer._Design-En-2021-02.png)
As the warm water flows down the drain, the incoming cold water flows through a spiral copper tube wrapped tightly around the copper section of the drain. This heats up the incoming cold water that goes to the water heater or fixture like a shower.
By preheating cold water, wastewater heat recovery systems help increase water heating capacity. This increased power really helps if you have a small water heater. You can also lower the water heating temperature without affecting performance.
Cost and installation
Costs for wastewater heat recovery systems range from $300 to $500. You will need a qualified plumbing and heating contractor to install the system. When building a new home, installation is usually cheaper. Payback is from 2.5 to 7 years, depending on how often the system is used.

The sewage heat exchanger is a tube-in-pipe design that consists of an integrated heat exchanger and a vertical section of copper pipe for wastewater. Waste water flows out through the inner pipe, while clean cold water passes through the outer pipe, where heat is transferred to it in the range of 15 ° C to 19°C due to outgoing hot water.
Requiring no regular maintenance, the sewage heat exchanger can be installed in new homes or retrofitted to existing ones.
Server Cooling: News from MagnoTherm Solutions, Roller, Beijer Ref and NTU
Extreme heat and cold can prevent IT equipment inside a data center from operating at peak efficiency and even disable critical equipment inside a server farm. It is not surprising that one of the main tasks of the designers and operators of any data center is to ensure accurate monitoring and control of the temperature in the turbine rooms. Increasingly advanced and cost-effective cooling technologies and systems are coming to their aid, including those described in the latest industry digest.
MagnoTherm Solutions GmbH receives €6.3 million to develop magnetic cooling systems of this technology and the organization of mass production of the corresponding heat and cold equipment.
MagnoTherm Solutions GmbH was founded in 2019 as a subsidiary of the Darmstadt University of Technology.
The startup team consists of experts in the field of permanent magnets and magnetic cooling.
Recall that the considered cooling technology is based on the magnetocaloric effect. We are talking about the ability of any magnetic material to change its own temperature and entropy when exposed to a magnetic field. Something similar happens during compression / expansion of gas / steam in traditional heat and cold technology.
Instead of using vapor refrigerants, magnetic refrigeration uses the magnetocaloric effect that occurs in iron-based rare earth alloys. These alloys heat up when magnetized and cool down when demagnetized. When the coolant circulates, heat and cold are transferred from the working material to the water through the heat exchangers.
Representatives of a young company claim that magnetic cooling devices are 40% more energy efficient compared to systems based on liquid compression / times. Moreover, they can be adapted to operating temperatures from -100°C to +80°C.
Due to the low operating pressure of 2-3 bar, maintenance is considered very safe and easy.
The startup notes that this technology allows stakeholders to save a lot of money in a short time, even though the purchase of cooling systems based on the magnetocaloric effect is more expensive.
Magnotherm engineers develop commercial cooling systems. The startup also plans to focus on customized solutions for cooling IT equipment in the data center and other electronics.
Singapore engineers propose to cool servers by spraying liquid on the CPU
A group of researchers from the Nanyang Technological University in Singapore (NTU) proposed a non-standard approach to cooling servers. Asian engineers came up with a strange but simple idea: spraying hot processors with a dielectric coolant to transfer heat to the environment as the coolant evaporates.
When testing the prototype, the team ran 12 servers inside a single 24U rack and sprayed dielectric fluid on the processors.
According to an article by Singaporean researchers published in the journal Energy in April 2023, the removal of excess heat from the system was carried out more efficiently than with conventional air cooling.
According to NTU experts, this type of spray cooling also reduces the carbon footprint of data centers by increasing the efficiency of supporting infrastructure and/or operating the CPU at elevated temperatures, allowing for overclocking. It is noted that the new cooling architecture allows for easy scaling and easily adapts to modern data centers.
A prototype system built by NTU scientists uses nozzles that spray a dielectric fluid onto each CPU. The liquid is condensed and collected for reuse in a closed system.
Most modern data centers are cooled by conventional, energy-intensive air conditioning systems. Immersion of IT equipment in a dielectric fluid, offered by several thermal equipment vendors including Submer, GRC and Asperitas, removes heat more efficiently and reduces power consumption.
Other vendors, including LiquidCool and Zutacore, offer even more advanced two-phase immersion cooling, which boils the liquid to remove even more heat.
The NTU team’s approach eliminates the giant tanks offered by conventional immersion system manufacturers and the piping used by proponents of two-phase server immersion cooling systems and direct contact liquid cooling systems. Radiators, which are used in conventional air cooling, are also abolished.
However, it is not clear which refrigerant Singaporeans are using. It is possible that PFAS (polyfluoroalkyl substances), which are considered hazardous to health, are used.
Data centers account for about 7 percent of Singapore’s total electricity consumption. There are very few renewable energy sources in this country, so the government rations data center energy consumption and tightly controls the issuance of permits for the construction of new data centers.
NTU engineers first proposed the idea of spray cooling inside data centers in tropical regions like Singapore back in November 2021 with a simpler prototype.
In January 2022, the team conducted the first performance evaluation of the system, after which they began to improve it.
Roller showcases 3 ranges of ultra-narrow unit coolers
Germany-based Roller showcases 3 ranges of ultra-narrow unit coolers VW, VM and VD. The devices are intended for commercial facilities. But they can also be used in server rooms where every cubic millimeter of available space counts.
The compact Roller VW column coolers can be installed in raised floors between racks or rows of racks due to their extremely narrow dimensions. The same applies to the new VD flat ceiling units. Devices from the VM range are designed for wall mounting.
Fans with electronic control of the speed of the impeller are used as standard for efficient operation. This allows you to save 80% of electricity compared to models without this function. The fans have an IP65 degree of protection and are pre-wired to the terminal box. The fan panels are removable for easy access to critical components.
Powder-coated aluminum housing protects devices from corrosion. A stainless steel housing is also available as an option. The devices use the technology of direct evaporation of the refrigerant. It is possible to use “natural” refrigerant CO2. For CO2 evaporators, the maximum pressure is 80 bar.
Beijer Ref Introduces Heat Recovery Unit SEC
UK-based Beijer Ref has designed and manufactured a heat recovery unit suitable for data center applications. When connected to existing refrigeration and air conditioning systems, the device, dubbed the SEC (Sustainable Energy Controller), is able to capture excess energy heat that would otherwise escape into the atmosphere and convert it into usable energy.
The unit collects all the heat available in the system and converts it into hot water. Not only does it work when the cooling system is in operation, it can operate in stand-alone mode, providing a source of thermal energy when the cooling system stops.
