100 L Becker & Wolf Wall‑Mounted Hot‑Water Heat Pump
Model BWHP100WM290 100 L All‑in‑One Cylinder
The BWHP100WM290 is a compact, wall‑mounted hot‑water heat‑pump cylinder designed for small homes and offices requiring more storage. It draws heat from the surrounding air using an energy‑efficient air‑source heat pump and stores it in a 100‑litre tank. Because heat‑pump water heaters move heat rather than create it, they deliver much higher efficiency than conventional electric resistance water heaters.
Attention: vacuuming and refrigerant filling must be carried out by a licensed technician

Why choose this heat‑pump cylinder?
- Reduce energy use. Traditional tankless‑coil boilers must stay hot to deliver hot water; in summer they cycle on and off and waste energy. Heat‑pump water heaters transfer heat instead of generating it and deliver much higher efficiency.
- Lower running costs. Heat‑pump water heater systems may cost more up front, but their lower operating costs generally offset the higher purchase price. The BWHP100WM290 draws just 220 W while producing nearly a kilowatt of heat.
- Eco‑friendly refrigerant. Uses R290 refrigerant with a very low environmental impact and harnesses renewable energy from the air to reduce reliance on fossil fuels.
- All‑season hot water without firing the boiler. Maintain hot water throughout the year without keeping a gas or oil boiler running during warm months, cutting fuel consumption and avoiding wasted energy.
- Quick delivery from stock. The 100 L cylinder is readily available for fast dispatch, helping you upgrade without delay.
- Expert UK support. Becker & Wolf’s UK‑based team offers knowledgeable advice before purchase and technical support after installation.
- Mobile showroom. Interested in seeing the technology in person? Qualifying customers can arrange for Becker & Wolf’s mobile showroom to visit their site or office for a hands‑on demonstration.
