How do I decide between a thermostatic and a manual radiator valve for an Arroll radiator?

A thermostatic valve lets you control room temperature automatically by sensing the air, so it's ideal for bedrooms and living areas where you want consistent comfort; the products in our range show thermostatic options with ornate or wooden heads. A manual valve gives simple on/off control and is fine for halls, garages or spaces you don't need to regulate precisely. Thermostatic valves often come paired with a lockshield in the same finish, so you get both function and a matched look.

What pipe and valve sizes are available and will they fit standard central?heating pipes?

The Arroll valves shown are 15mm, which is the standard size for most domestic central heating pipework. Pipe sleeves and collars are offered in 130mm and 300mm lengths with an 18mm bore to slip over typical 15mm pipes and give a neat finish. If your plumbing uses 15mm pipes, these parts will match; for other sizes you'll need to confirm your pipe diameter first.

Which finishes will best complement an Edwardian aluminium radiator?

Arroll's Edwardian aluminium radiators come in white or anthracite, and the accessory finishes you can match include chrome, antique brass, Old English brass, brushed nickel and black nickel. For a white radiator, chrome or brass will give a crisp traditional look; for anthracite, black nickel or antique brass creates a richer, more contemporary contrast. Picking the same finish for valves, collars and wall stays keeps the design cohesive.

What are pipe sleeves and collars used for, and how do I choose the right length?

Pipe sleeves and collars hide the gap where pipes enter the floor or wall and give a tidy, finished appearance; they're included in our range in two lengths, 130mm for short concealed runs and 300mm for longer visible runs. Choose 130mm if the exposed pipe is minimal, from the floor to the valve; use 300mm if you have a long vertical run down a wall that you want to dress up. The 18mm bore fits standard 15mm pipework.

Do Arroll wall stays suit traditional column radiators and lightweight aluminium models?

Yes; the Luxury Wall Stays in chrome or antique brass are designed to secure classic column radiators like Arroll's Edwardian range. Even though the aluminium Edwardian radiators are lightweight and corrosion‑resistant, a wall stay gives extra stability for taller or heavier installations and keeps the historic look authentic. Match the stay finish to your valves and collars for a polished result.
