Control Knobs

What is a Control Knob?

A control knob is a rotary control used to provide input to a device when grasped by an operator and turned, so that the degree of rotation corresponds to the desired input. A control knob is also known as a tap handle, this is used to control power to appliances and to control the temperature of heating and hot water. Usually on a boiler there is a  temperature control knob, and also central heating and domestic hot water control knob. Manufacturers include, Baxi, Ideal, Vailliant, Glowworm and Vokera.

It is important to take your time to find the right Control Knob for your Gas Boiler. We have a large range in stock at DHS and if you are unsure please give us a call.
