Heating products for UK homes: controls and thermostats, radiators and valves, pumps, cylinders and the kit around a boiler.
Everything here is written by Nick Jolliffe, who spent 16 years running plumbers merchants across the south of the UK and a couple more with an independent merchant. Selling to the people who fit this equipment for a living tells you things a spec sheet does not: which brands come back, which ones fitters specify by name, and when the expensive option is genuinely worth it.
A word of caution on this category in particular. Anything involving a gas appliance or an unvented cylinder legally needs a Gas Safe or G3 registered engineer. These guides are here so you can have a competent conversation with the person doing the work, not so you can do it yourself.
No team, no payment for placement. Corrections are welcome.
A TRV shuts a radiator off once the room reaches the temperature you set. What the numbers really mean, where a TRV must not go, how to free a stuck pin, and whether smart valves pay back at the current gas price.
Six oil-filled radiators verified live on Amazon UK, with the running cost arithmetic worked through at the October 2026 Ofgem cap, the sizing rule of thumb, and an honest look at why no electric heater is cheaper to run than any other.
Where the cold part of the radiator is tells you what is wrong. Cold at the top is air and bleeding fixes it. Cold at the bottom is sludge and bleeding does nothing. A symptom-by-symptom guide to every cold radiator fault, and the stop line where the job legally needs a registered engineer.
There is no single filling loop design. Identify whether you have an external braided loop, a keyed filling link or a keyless lever, then follow the right procedure, set the correct pressure for your boiler, and know what to do if you overshoot.
