Oxyvent Optimising Heating Management System

Solid Fuel
There is finally a solution for combining solid fuel with oil or gas, The Oxyvent Tank is the only product available that gives complete control over the water temperatures in both boilers.
The cracking and banging noises that are associated with solid fuel is called Thermal shock, which is the sudden mixing of hot and cold water temperatures. The Oxyvent system is set up to control the water temperatures in the solid fuel boiler by not letting the water temperature in the boiler go over 60oC and keeping the boiler return temperature at 50oC.
The cold return water coming back from the radiators is mixed inside the Oxyvent Tank and cannot return back to the boiler until its temperature is raised back up to 50oC. This design prevents thermal shock from taking place inside the boiler and eliminates banging and cracking.
Oxyvent Tank benefits
- Removes the air automatically and no need for flushing the system
- Increase the flow rate in each loop to 3 litres p/m
- Removes thermal shock and decreases the heat up time by half
- The fuel savings achieved with the Oxyvent Tank are enormous
Oxyvent Tank specifications
- The Oxyvent Tank has been tested by experts at Trinity College Dublin
- The Oxyvent Tank is manufactured in the Netherlands to ISO 9002; ISO 14001. It has a Certification of Design and a manufacturing process that is approved by TUV
- Dimensions: 375mm X 295mm X 295mm Weight: 28 kg
- Output: 44KW, 150,000 BTU/hr
- Maximum pressure: 3 bar typical
It is compatible with most central heating systems, either open vented or pressurised:
- Gas
- Oil
- Solid Fuel
- Radiators
PV+

Are you interested in getting 20% more generation from your Solar PV system?
The new PV+ from matt:e Ltd keeps you generating for longer meaning a faster return on investment for existing and new systems alike.
- Works with any pv system manufacturer
- Simple to fit or retrofit
- Low cost / high carbon benefit
Did you know that... when your PV system is generating at full capacity, your inverter could be in over-voltage mode and not generating at all?
This potential loss in generation could be costing you £££’s
How does the PV+ help?
By monitoring the incoming supply voltage, the PV+ unit allows the Solar PV inverter to compliantly stay in circuit for longer, preventing nuisance over voltage shut down and keeping you generating for longer. Meaning a faster return of investment for existing and new systems alike.
Additionally, as excessive voltage is given up as heat in electrical appliances, running the PV inverter closer to it’s designed voltage will reduce stresses caused by overheating and potentially help increase it’s operating life.
Installation
The PV+ unit has been design to simply replace the lockable AC isolator located next to the consumer unit. With simple wire in wire connection all housed in a compliant metal case installation could not be easier.
Product Features
- BS7671 : 2008 amendment 3 compliant non combustible metal enclosure*
- matt:e Ltd type tested software
- Lockable mains AC isolator
- Designed and built solely in the UK
Solar PV Batteries

The ground-breaking X-Hybrid is much more than just an inverter. It is an intelligent, integrated system that manages the energy you generate effectively and efficiently. The X-Hybrid works by storing surplus energy in batteries for later use. The Hybrid ‘E’ also has built-in EPS (Emergency Power Supply) functionality, allowing the end user to make use of their stored energy in the event of a power outage. The ‘E’ series can also work as a completely off-grid system.
