Buying guide

Specify John Guest with confidence

Heat loss and output

Calculate each room’s heat demand and usable floor area. A high-output pack is a design choice, not a substitute for checking the complete floor construction.

Loop and manifold plan

The number of circuits and manifold positions should be set before buying pipe and controls.

Overlay or conventional

Check finished floor height, substrate, insulation and covering for the selected system.

Aura compatibility

Match thermostat, hub and wiring/control pack types. Confirm product generation and wired or wireless operation before mixing components.

Good to know

John Guest questions, answered

Are John Guest pipe and UFH kits the same product category?

No. Pipe is one component; kits bring together components for a planned floor heating installation. Check kit contents before adding separate pipe or controls.

When would I use an overlay board?

It can suit renovation where a suitable existing subfloor and limited build-up height favour an over-floor construction.

Can I mix Aura wired and wireless controls?

Only use combinations supported by the exact Aura and control-pack models. Check the product specifications and installation instructions.
