REMEHA FUSION
OVERVIEW
4 5
ONE SYSTEM,
MANY ADVANTAGES
Accessories
Vibration dampers for stand-alone heat
pumps aswell as cascade configurations
0-10V interface
CAN-OpenTherm interface
Trace heating for all cascade configurations
(2, 3, 4 and 5 GAS HP)
Remeha Fusion heat pumps can be used in:
Existing buildings, including base load optimisation
in installations with a medium to high
heating capacity
Swimming pools, hotels, healthcare institutions
Industry: for heating process
water and climatecontrol
Retail: individual stores as well as
larger shoppingcentres
Offices
Industrial construction
Apartment blocks
In general, the Remeha Fusion is very well-suited
to applications in both existing and new buildings.
The Remeha Fusion is equipped with a two stage frost
protection as standard with the circulating pump
being switched on for the first stage and if necessary
the burner is fired in conjunction with the circulating
pump for the second stage frost protection, trace
heating is also available as an optional extra. If for
any reason that the gas or electrical supplies cannot
be guaranteed during colder weather, then a water/
antifreeze mixture should be considered, further
advice should be obtained from the Renewables
technical department on 0118 978 3434.

modificationsrequired
No three-phase current required (with the
exception of fully assembled skids with
multiple pumps)
Can be installed in combination with
existing units
Can be used in new and existingbuildings

2
emissions
Suitable for pre-heating domestic hot water
Remeha maintenance service available
10-year warranty on the sealed part of the
heat pump
Unit

Output 35kW
Modulating from 100%-50%
Control via 0-10V, or on/off
High efficiency even at low
outsidetemperatures
Problem-free operation at extreme
outside temperatures
Built-in control strategy to protect
againstfreezing
Maintains efficiency at high
dischargetemperatures
Skids (cascade frames)
Fully pre-assembled cascade frames
(electrical, gas and condensation connections
already present)
Cascade frames available in four versions,
varying in output from 70kW to 175kW
Fitted with energy-efficient modulating pumps
for a constant deltaT
Option of hydraulically isolating an individual
heat pump on a skid from the other heat
pumps (for example during repair/
maintenance)
Equipped as standard with thermostat pockets
inside the insulation of the main pipes, allowing
a trace heating system to be fitted if required
(optional)
As an option, the main flow and return pipes
can be fitted with a trace heating, which is
always advisable in the UK
