Which radiator for which room?

The right radiator depends on the room, your boiler and your plans. We advise you before fitting anything.

  • Steel panel radiator

    The most common

    The central heating standard: good efficiency, a reasonable price, and many sizes to fit existing connections.

    • Heats up quickly
    • Available in a vertical version
    • Works with any boiler
  • Towel rail

    For the bathroom: it heats the room and dries your towels. Connected to the central heating, electric or dual-fuel.

    • Hot water or electric connection
    • Many sizes and finishes
    • Ideal when renovating a bathroom
  • Low-temperature radiator

    A larger heat exchange surface to heat with cooler water: the ideal partner for a condensing boiler or a heat pump.

    • Gets you ready for a heat pump
    • Better condensing boiler efficiency
    • Gentler, more even heat

What we do on your radiators

  1. 01

    Replacement

    An old radiator that leaks or heats badly? We replace it with a suitable model, reusing the connections where possible.

  2. 02

    Adding

    A new room, a conservatory, a loft conversion: we extend the circuit and add radiators sized for the space.

  3. 03

    Moving

    A renovation, a new kitchen: we move a radiator and redo the pipework neatly.

  4. 04

    Thermostatic valves

    Thermostatic valves fitted or replaced so you can set each room and avoid heating for nothing.

    Refilling, bleeding, re-pressurising and balancing, so every radiator heats as it should.

Good to know

A radiator that heats badly doesn't always need replacing

Cold at the top, hot at the bottom? There's air in it: bleeding is often enough.

Cold at the bottom, hot at the top? Sludge has settled: power flushing will bring the heat back to the whole circuit.

Making the right choice

Radiators and heat pumps: plan ahead

Thinking of switching to a heat pump in the next few years? A heat pump heats with cooler water than a traditional boiler: so your radiators need a large enough heat exchange surface.

By choosing radiators sized for low temperatures now, you avoid having to replace them a second time. We advise you on the right balance between comfort, budget and future-proofing.

    Intervention très rapide un vendredi soir et un jour férié pour une fuite urgente sur notre chaudière. Le technicien a identifié le problème et est revenu le lendemain pour remplacer la pièce et tout remettre en service. Service efficace et réactif dans une situation d'urgence.
