Heating

From a single replacement radiator to a complete central heating system, ALPHA & CO covers the whole heating range online: steel panel radiators, vertical designer radiators, towel warmers, electric radiators, boilers and cylinders, underfloor heating with manifolds and accessories, room thermostats (wired, wireless or smart), thermostatic valves and circulation pumps. Our references come from the Desco, Van Marcke and ALPHA&CO catalogues — the same ranges Belgian heating engineers install every day. Installers find their usual brands with volume discounts; homeowners buy exactly the radiator they need online, with matching connection sets and valves. Delivery in Belgium and Luxembourg takes 3 to 6 working days and is free from €150 — reached with a single radiator. For a complete project (central heating, underfloor heating or a heat pump package), request a quote: we price all the material in one offer.

Frequently asked questions

What radiator output do I need for my room?

Allow roughly 70 to 100 W per m² in an averagely insulated home with 2.5 m ceilings, and 50 to 60 W/m² in a recent, well-insulated house. For a 12 m² bedroom, aim for 900 to 1,200 W. Slightly oversizing pays off: a larger radiator runs at a lower temperature, which improves the efficiency of a condensing boiler.

Which thermostat should I choose for central heating?

A programmable room thermostat is enough for a conventional boiler. With a condensing boiler, prefer a modulating (OpenTherm) thermostat: it continuously adjusts the water temperature and cuts consumption. Smart models add remote control and presence detection. Just check compatibility with your boiler brand — our team can help.

Steel or aluminium radiator?

Steel offers the best price-to-output ratio and good thermal inertia: it remains the standard for central heating in Belgium. Aluminium heats up faster and is lighter, useful in renovations or rooms used occasionally. In both cases, check the connection centres so you can replace without altering the pipework.

Is underfloor heating compatible with my boiler or heat pump?

Yes: underfloor heating runs at low temperature (30 to 45 °C), making it the ideal partner for a heat pump or condensing boiler. You need a manifold with balancing valves and, if the same circuit also feeds high-temperature radiators, a mixing unit. All these components are available in this category.

How are bulky radiators delivered?

Radiators and boilers are delivered in Belgium and Luxembourg within 3 to 6 working days, packed for transport. Delivery is free from €150, so practically always for a radiator. For vertical models, check dimensions and access before ordering.

Do you offer trade pricing for heating engineers?

Yes. For a complete job — central heating, underfloor heating, boiler replacement or a heat pump package — send your material list via the quote page. We apply volume discounts and group everything into a single delivery.
