Choosing The Right Bay Window Radiator: A Helpful Guide

Measuring For Radiators in Windows: Getting the Right Fit

Ensuring the right fit for your bay window radiators begins with precise measurements. When measuring for height, maintain a 4″ gap between the top of the radiator and the sill for an aesthetically pleasing look. Consider opting for a deeper model or adding an additional radiator if more heat is needed in the space. For those with curved walls in their bay window spaces, our curved steel column radiators offer a practical and sleek heating solution designed to suit the distinctive architectural features

Measuring for a Radiator in a Square Alcove or Bay

When situating a radiator in a square-sided alcove or bay, attention to detail is key. Match the radiator width to that of the window in a square bay and account for valve space by allowing approximately 4″ on either side. Ensure a minimum of 2″ from the pipe to the wall for easy manual adjustments.

Measuring for a Single Radiator in an Angular Bay Window

A single radiator in an angular bay window exudes classic simplicity. To maintain a well-proportioned look, ensure the valves do not extend beyond the bay corners. Keep the radiator within the dashed lines in our diagram for optimal sizing. Allow approximately 4″ on either side for valves. For a 58″ distance between the dashed lines, aim for a radiator length around 50″, striking the right balance.

Measuring for Multiple Radiators in an Angular Bay Window

Arranging multiple radiators in an angular bay requires thoughtful spacing. Keep each radiator, including valves, within the width of the window reveal, with an additional 4″ on each side for valves. For more flexibility, follow the guidance in our diagram, allowing approximately 6″ from the outer edge of the valve to the bay corner—ideal for accommodating floor-length curtains and maintaining a harmonious look.
