Choosing the Right Radiator Architecture

Match room volume, wall space, and interior decor to the ideal radiator format:

Slim Profile

Type 11 (K1) Single Convector

A single steel panel with one set of convector fins. Ultra-slim profile (under 60mm projection) ideal for narrow hallways, landings, and small box bedrooms.

Hallways & Small Spaces
Maximum Heat Power

Type 22 (K2) Double Convector

Two steel water panels sandwiching two high-density convector fin sets. Delivers twice the radiant and convective heat output in the exact same wall width.

High-Ceiling Tenements & Lounges
Contemporary Style

Vertical Designer Columns

Tall 1800mm vertical anthracite or white columns that take up zero horizontal furniture wall space while delivering exceptional heating output.

Why Standard Online Radiator Calculators Fail in Glasgow

Generic BTU calculators assume standard modern 2.4-metre ceilings. In Glasgow's sandstone tenements in Shawlands, Partick, and Dennistoun, ceiling heights routinely exceed 3.2 to 3.8 metres.

Because heat naturally rises, standard radiators leave the living zone cold while pooling heat near decorative ceiling cornicing. We apply a verified 25% to 35% tenement cubic correction factor to ensure your living spaces stay genuinely comfortable.

Tenement BTU Correction Factor:

Standard New Build (2.4m ceiling): 1.0x Base BTU
Tenement Ground/Mid Floor (3.2m ceiling): 1.28x BTU (+28%)
Top Floor Tenement (3.6m + Roof Heat Loss): 1.38x BTU (+38%)
Room-by-Room Zone Control

Thermostatic Radiator Valves (TRVs) Cut Fuel Waste

Old manual wheelhead valves let radiators blast heat continuously. Fitting liquid-sensor TRVs allows you to set precise target temperatures for each room (e.g. 21°C in living rooms, 17°C in bedrooms), cutting gas consumption by up to 18% automatically.

Radiator Replacement FAQs

Essential guidance on upgrading radiators in Glasgow properties.

Can I swap a radiator without changing the existing pipework? +

Yes. If the new radiator has the same width as your old one, we use adjustable telescopic radiator valve tails to connect directly to your existing copper pipework without lifting floorboards.

Can weak lath-and-plaster walls support heavy double convector radiators? +

In historic Glasgow tenements with lath-and-plaster partition walls, heavy water-filled radiators require solid timber stud anchors or heavy-duty floor-mounted radiator support feet to transfer weight safely off the plasterwork.
