Warmflow heat pumps
Warmflow Zeno heating, designed around your home.
Enerus designs and installs Warmflow Zeno R290 air source heat-pump systems across the North East—combining the outdoor unit, Nero hot-water cylinder, controls and heat emitters in one calculated design.

Three modulating Zeno R290 units.
Select a model to understand its published operating range. Enerus confirms the final selection from heat loss, design temperatures, hot-water demand, electrical supply, sound and siting.
AS01-R290
The smallest unit in the current family, with a published modulating output range from 3 to 9 kW.
- 1167 mm wide and 795 mm high
- Published COP of 4.79 at A7/W35
- Integrated variable-speed heating pump
The model’s maximum figure is not automatically its available output at the local winter temperature and intended flow temperature.
One connected R290 platform
High-temperature capability with remote access.
Warmflow publishes leaving-water temperatures up to 75°C, integrated variable-speed circulation and Warmlink cloud connectivity across the Zeno R290 family.
- R290 refrigerant with published GWP of 3
- All three units use a 230 V single-phase supply
- Published sound pressure levels from 41 dB(A)
- Built-in 4G SIM for Warmlink connectivity*
Warmflow Nero heat-pump cylinders
Four dedicated hot-water sizes.
Nero heat-pump cylinders are designed to work with the Zeno range and use a high-performance heat exchanger to support faster recovery.
HP170UV to HP290UV
Four cylinder sizes cover a range of household hot-water requirements. The correct capacity is selected from occupancy, baths, showers, simultaneous use, recovery and the available installation space.
- Published cold-water capacities of approximately 165–281 litres
- High-performance heat exchanger and published recovery times of 21–34 minutes
- Mains-fed unvented arrangement with inlet group supplied
- Published V40 hot-water volumes from 229 to 401 litres
Warmflow publishes a 25-minute heat-up time to 60°C from cold for the 170-litre model under its stated test conditions. Real recovery depends on heat-pump output and operating conditions.
Controls and connectivity
The controller is the brain of the Zeno system.
Warmflow combines a user-facing touchscreen with Warmlink remote connectivity and a dedicated wiring centre for the wider heating system.
Touchscreen interface
The user-facing controller covers heat-pump and system settings from one interface.
- Heating and hot-water control
- System status and adjustment
- Configured during commissioning
Warmlink
Remote control and diagnostic access through Warmflow’s cloud platform using the unit’s built-in 4G SIM.
- No household Wi-Fi required*
- Remote control capability
- Supports remote diagnostics
Zeno Wiring Centre
Brings heating demands and associated system connections together in a dedicated control enclosure.
- Neater system wiring
- Matched to the Zeno installation
- Specified around the selected hydraulic design
*Warmflow states Warmlink access is currently complimentary and subscription-free, but future charges may apply; GSM access depends on mobile-network coverage.
The Enerus design process
A Warmflow unit is one part of the system.
Calculate the demand
Room-by-room heat loss establishes the required duty, emitters and intended water temperatures.
Build the package
Zeno unit, Nero cylinder, controls, hydraulics, electrical supply and siting are brought into one proposal.
Commission and support
Flow rates, temperature control, schedules, connectivity and handover are completed as one finished system.
Common questions
Warmflow heat-pump FAQs.
What Warmflow Zeno outputs are available?
The current R290 range contains 9, 15 and 22 kW units, with published modulation ranges of 3–9, 5–15 and 8–22 kW respectively.
Are the Zeno R290 heat pumps single phase?
Warmflow currently lists all three Zeno R290 units for a 230 V single-phase electrical supply. The property supply and maximum electrical demand must still be assessed.
What sizes are the Nero heat-pump cylinders?
The dedicated heat-pump cylinder family includes 170, 200, 240 and 290 litre product sizes.
Can a Warmflow heat pump produce high-temperature water?
Warmflow publishes leaving-water capability up to 75°C. That does not mean a system should routinely operate at its maximum temperature; Enerus designs for the lowest practical water temperature.
Does Warmlink need the homeowner’s Wi-Fi?
Warmflow states that each Zeno R290 unit includes a built-in 4G SIM, so Wi-Fi or a CAT5 connection is not required. Access depends on mobile-network coverage and future service charges may apply.
Does a Warmflow heat pump qualify for grant support?
Warmflow states the range qualifies for applicable government support, subject to the property, installation and scheme conditions.
