Frequently Asked Questions
What size radiator do I need?
To figure out what size radiator you may need for your room, you can use a radiator BTU calculator tool online.
How does a radiator work?
Radiators work through a heat transfer process called convection. This means that when water in the radiator is heated, the surrounding air is also heated up via convection and this hot air is then moved around the room as the air circulates.
How to measure a radiator?
Take your tape measure from the lowest point of your radiator to the highest.
Can you paint radiators?
Yes, you can paint radiators.
When to bleed radiators?
Radiators need bleeding when they have air trapped inside of them. If your radiator is cold at the top, but warm at the bottom, it usually means they need to be bled.
