KERS MEV

KERS MEV SERIES

Indoor Heat Pump - Hot Water - Heat Recovery Mechanical Extract Ventilation. Converting waste heat energy from bathrooms and kitchens to low cost, renewable hot water.

INDOOR HEAT PUMP

KERS MEV-W160
KERS MEV-W230
KERS MEV-W300

The eco-friendly KERS MEV indoor heat pump is a combined hot water, heat recovery and MEV system with storage cylinder. The all-in-one design replaces mechanical ventilation and heat recovery system with only one penetration through the building.

USES

SCHEMATIC

REMOVABLE COVER

For ease of servicing and maintenance the top cover is removable to allow full access to all the heat pump components

24/7 YEAR ROUND EFFICIENCY

External heat pumps are less efficient as the outside temperature drops. The KERS MEV indoor heat pump recycles a constant 20c of waste energy from within your building and converts this to low-cost renewable hot water

ABUNDANCE HOT WATER AVAILABLILITY

We use a large-surface condenser that heats up the water faster due to it’s larger heat transfer surface. This can optionally be augmented with an electric heater upgrade in extreme cases such as commercial gym showers with non-stop peak flow

FUNCTION PACKED CONTROLLER

A multi-function controller provides optimal management for all operations with legionella, fan speeds, weekly timer and diagnostics

INCREDIBLE EFFICIENCY AND SAVINGS

For every 1KW of energy consumed, our KERS system can produce upto 4.5KW of thermal energy

HEATERLESS DESIGN

Most heat pumps rely on an electric immersion heater to achieve higher water temperatures. Our heaterless design produces hot water temperatures of upto 65oc solely using our heat pump technology, resulting in greater energy savings

GREAT BENEFITS

High efficiency – for every 1kw input up to 4.5kw output
Provides both hot water and ventilation
Heaterless design – achieves 65°C without the need for immersion
Removes condensation and humidity
No external condenser
Compact design to reduce space loss
Easily serviceable with bespoke design, no requirements for removal of ductwork
Weekly legionella program

Over 330% efficient

The KERS MEV recovers all of the waste energy and using heat pump technology achieving 330% efficiency as recorded in SAP

HEATERLESS DESIGN: WHY IS IT A BIG DEAL?

Most heat pumps rely on an electric immersion heater to achieve higher water temperatures. Our heaterless design produces hot water temperatures of up to 65c solely using our heat pump technology, resulting in greater energy savings.

GUARANTEED YEAR-ROUND EFFICIENCY 24/7

External heat pumps are less efficient as the outside temperature drops. Our KERS indoor heat pump recycles a constant 20c of waste energy from within your building and converts this to low-cost renewable hot water.

CONSTANT AVAILABILITY

We use an external large-surface condenser that heats water up faster due to its larger heat transfer surface. This can optionally be augmented with an electric heater upgrade in extreme cases such as commercial gym showers with non-stop peak flow.

INCREDIBLE EFFICIENCY AND SAVINGS

For every 1KW of energy consumed, our KERS system can produce up to 4.5KW of thermal energy.
