The Becker & Wolf BWHP200R290 is a 200-litre floor-standing, all-in-one hot water heat pump that combines the compressor, fan, heat exchanger and storage tank in one self-contained unit. There is no outdoor unit and no refrigerant pipework to run between components, so installation comes down to water, electrical and condensate connections. It is factory-tested and plug-and-play ready.
It uses R290 (propane) refrigerant with a GWP of 3 and a 400 g charge, carries an A+ ErP energy class, and delivers a rated COP of 4.45 (3.677 to EN 16147) from a 2.8 kW rated heating capacity. A 2 kW electric element lifts the water to a maximum of 75 °C and backs up the heat pump in cold conditions, while Wi-Fi control through the Becker & Wolf app and a supplied G3 unvented kit make it a practical replacement for gas or direct-electric hot water in family homes and utility rooms.

Unvented hot water and flammable refrigerant: competent installation required
This is a mains-pressure (unvented) storage system. Installation, commissioning and the safety discharge arrangements must follow Building Regulations Part G3 and be carried out by a suitably qualified G3-competent installer. Part G requires a potable expansion vessel and a tundish in the system, fitted by the installer, and the G3 kit includes a TMV (thermostatic mixing valve) to guard against scalding during the sterilisation cycle. The unit contains R290 (propane), a flammable refrigerant, in a factory-sealed circuit. Follow the manufacturer's installation manual for location, clearances and room-size requirements, and never modify the refrigerant circuit.
Hot water only: not a space heating replacement
This unit heats domestic hot water only and does not provide central heating. It replaces gas water heaters or direct-electric cylinders for hot water; keep a separate heat source for space heating.
Operating range, space and electrical supply
The heat pump works in ambient air from -7 °C to +43 °C, and the electric element extends operation down to -15 °C. Install on a level base at least 50 mm thick and at least 700 x 700 mm, indoors and protected from rain. For indoor installation in a sealed, unvented room the manual states a minimum room area of 253 m² (this does not apply to vented cupboard spaces); allow at least 300 mm either side and 500 mm above the unit. Use a dedicated supply, 220–240 V, 1-phase, 50 Hz, with a maximum input of 3000 W (13.3 A). Mains inlet pressure should be 0.15–0.50 MPa: add a booster pump below, or a pressure reducing valve above.
What is supplied
The unit ships with a G3 unvented safety kit and the Becker & Wolf Wi-Fi module for app connection, plus the PTR valve and condensate drain fittings listed below.
Key features
All-in-one design
Compressor, fan, heat exchanger and tank sit in one unit with a micro-channel condenser wrapped around the tank, so refrigerant never touches the water. No outdoor unit and no refrigerant pipework.
Large 200 L capacity
200 litres of enamelled storage with an XL tapping cycle and a rated hot water production of 60 L/h, sized for medium-sized households.
Three operating modes
Standard (15–60 °C), Hybrid (heat pump to 60 °C, then the element up to 75 °C) and Electric mode, plus a Boost function for fast recovery.
Automatic sterilisation
A weekly sterilisation cycle is on by default: the water is heated to 70 °C and held at 65–70 °C for 30 minutes. Manual start is also available.
Wide range and ducting
Heat pump operation from -7 °C to +43 °C, extended to -15 °C with the element, automatic defrost, 48 dB(A) running and a 150 mm air duct option (up to 6 m, 3 bends).
Wi-Fi app control
The Becker & Wolf app (iOS and Android) sets temperature and mode, runs repeat-day timer schedules, shows status and error codes, and can share the unit with family members.

Frequently asked questions
Does it need an outdoor unit?
No. The compressor, fan, heat exchanger and tank are all integrated in one unit, so there is no outdoor unit and no refrigerant pipework between components. You connect water, electrics and a condensate drain.
Can it replace my boiler?
It replaces gas or direct-electric hot water production only. It is a hot water heat pump and does not provide space heating, so a separate heat source is still needed for central heating.
What temperatures does it work in?
The heat pump works in ambient air from -7 °C to +43 °C, and the 2 kW element extends operation down to -15 °C. The default water temperature is 55 °C. When ambient is low and the tank is cold, anti-freeze protection starts the element, so keep the unit powered through freezing weather.
Can it reach 75 °C?
Yes, using the electric element. The heat pump heats to 60 °C; in Hybrid or Electric mode the element carries on to setpoints up to 75 °C.
What does the sterilisation cycle do?
The unit heats the tank to 70 °C and holds 65–70 °C for 30 minutes. It runs automatically every 7 days by default when the setpoint is below 70 °C, and can also be started manually.
Is a G3 kit included, and who can install it?
Yes, it is supplied with a G3 unvented kit. Because this is an unvented system, it must be installed and commissioned by a G3-competent installer in line with Building Regulations Part G3, with a potable expansion vessel and tundish in the system.
How do I control it remotely?
Download the Becker & Wolf app (iOS or Android), create an account and a home, then add the unit under Large Home Appliance > Smart Heat Pump (Wi-Fi) after holding the power and up keys for 5 seconds. You can then set temperature and mode, schedule repeat timers, view errors and share access with family members.
Is this the right size for my household?
As a guide, a 200 litre unit suits around 3–4 people. Peak demand, bath use and the number of bathrooms all matter, so size for your busiest day rather than the average.
What maintenance does it need?
Lift the PTR valve lever every six months, clean the Y-filter and check the magnesium anode annually (typically replaced about every two years). Keep the unit powered below freezing, and drain the tank if it will be unused through winter.
Can the air be ducted?
Yes. The floor-standing models have a 150 mm air duct option with vertical air discharge. Keep the total duct length to 6 m or less, with no more than 3 bends, insulate ducting to avoid condensation and fit a filter at the inlet. Install the unit indoors, not exposed to rain.
Is there a water quality requirement?
The manufacturer specifies limits including calcium hardness 80 mg/L or less, chloride 50 mg/L or less and pH 7.5–8.0. Where mains water exceeds these, softening treatment is required.
