Product Information

A simple but essential component for any well-designed heat pump system. The 300L buffer tank helps protect the compressor, lower running costs and deliver more consistent comfort.

Stainless steel construction. Reduces short cycling of the heat pump. Improves overall system efficiency and longevity. Provides substantial thermal storage for more stable heating. High capacity ideal for larger properties and higher-demand systems. Compatible with GreenLine and other heat pump systems. Fitting kits available to meet UK regulations.

Features and benefits

Must be installed by a qualified person in accordance with current UK regulations. When used in unvented systems, the correct safety and control valves (including expansion vessel and pressure relief) must be fitted to meet G3 requirements. Do not exceed the maximum working pressure or temperature stated on the unit. Ensure the tank is properly supported and all connections are correctly sealed. Switch off power to any connected heat pump or system before carrying out maintenance. Follow all installation instructions supplied with the tank and fitting kit.

FAQs

Got questions?
We've got answers

What does a buffer tank do in a heat pump system?
A buffer tank stores a volume of heated water to keep flow and temperature consistent. It helps your heat pump run smoothly rather than constantly switching on and off, improving performance and overall comfort.
Do I need a buffer tank with my heat pump?
In most cases, yes. Especially in homes with multiple zones or lower water volume systems. It protects the heat pump, improves stability and helps avoid unnecessary wear over time.
Will a buffer tank improve efficiency?
It can. By reducing short cycling and allowing the heat pump to operate more efficiently, a buffer tank helps the system run in its optimal range, which can lower energy use over time.
What size buffer tank do I need?
This depends on your system size, property and heating setup. Choosing the right size ensures proper flow and maximum efficiency. Our team can quickly recommend the ideal tank for your project.
