Frequently Asked Questions

Common questions about heat pump cylinder installation

What makes a cylinder suitable for heat pumps?

Heat pump cylinders need larger coil surface areas (4.5m²-6.0m²) compared to standard cylinders (1.5m²-2.0m²) because heat pumps operate at lower temperatures (35-45°C vs 60-80°C). The larger coil compensates for the lower temperature difference, maintaining fast reheat times and efficiency.

How long does heat pump cylinder installation take?

A complete heat pump cylinder installation typically takes 6-8 hours including removal of the old cylinder, installation of the new unit, pipework modifications, safety valve installation, and G3 compliance testing. Commissioning and final testing takes an additional 2-4 hours the following day.

Can I get the £7,500 BUS grant for cylinder installation?

The £7,500 Boiler Upgrade Scheme grant is available when you install a complete heat pump system including a compatible cylinder. The grant is administered by the MCS-certified installer who fits the heat pump itself. I install the G3-certified hot water cylinder and work alongside your heat pump installer — I'm happy to recommend a trusted MCS-certified installer if you need one.

What's the difference between Heat Geek Super and Vaillant uniSTOR?

Heat Geek Super offers the largest coil surface area (6.0m²) for maximum efficiency with heat pumps, while Vaillant uniSTOR provides 5.2m² coil area with a premium 25-year warranty. Heat Geek is typically better for maximum performance, while Vaillant offers exceptional reliability and warranty coverage.

Do you need G3 certification to install heat pump cylinders?

Yes, absolutely. G3 certification is a legal requirement for installing unvented hot water cylinders in the UK. This includes all heat pump cylinders as they operate under pressure. G3 certification ensures installers understand safety requirements, pressure relief systems, and compliance testing. Always verify your installer holds current G3 certification.
