⚡ At a Glance
- • Temperature Control: Adjustable between 7 and 29°C with five selectable settings and frost protection
- • Best for: Homeowners and landlords needing a quick, standard replacement for radiator heads
- • Not ideal for: Radiators that do not use M30 x 1.5 threaded valves or specialist industrial systems
Universal M30 x 1.5 threading fits industry-standard radiator valves. Durable ABS construction resists bangs and scuffs while built-in frost protection guards against freezing.
Quick Replacement – With universal M30 x 1.5 thread compatibility
M30 x 1.5 is the normal industry standard threading used on most radiator valves, allowing direct fitment without adapter parts. The head can be mounted in either horizontal or vertical orientations.
Fast swaps reduce downtime during maintenance. A standard thread means compatibility across a wide range of manufacturers and models.
Stable Room Temperatures – Thanks to five-step temperature control
A simple five-setting mechanical thermostat adjusts valve opening to regulate flow and maintain approximate room temperatures between 7 and 29°C. Each setting corresponds to a different valve position for coarse temperature control.
Easier to keep rooms comfortable without fiddly adjustments. Users can select a setting and leave it, with predictable temperature behaviour.
Long-Lasting Finish – With tough ABS construction
High-quality ABS resists impact, scuffs and general wear while retaining its white finish. The design purposefully prioritises robustness for both domestic and commercial environments.
Appearance stays neater for longer in busy homes or rented properties. A one-year guarantee against manufacturing defects provides additional reassurance.
