FAQ Boilers

How often should I get me boiler serviced?

Your boiler should be serviced annually. The best time to do this is during the summer months when installers are not so busy.

The benefits of an annual service would include ensuring your warranty is valid, if applicable, and minimize the risk of future breakdowns. All of this will give you peace of mind and save you money by helping your boiler to work at maximum efficiency.

What type of boiler do I need?

The type of boiler you need will depend on the size of your house, plus your hot water requirements. We can help you choose the most appropriate boiler for your home.

The hot water supply from my combination boiler fluctuates. Is this correct?

Depending on heat output, combination boilers can only supply a one tap at a time. Turning on additional taps will reduce the flow of hot water. If the water is not hot enough you may have to reduce the flow (by turning the tap down) to increase the temperature. This may be necessary especially in winter when the water supply to the boiler is colder.

What is a thermostatic mixer shower?

A thermostatic mixer shower will maintain an exact water temperature for the duration of your shower, protecting you from any sudden changes in the water supply to the shower (i.e. if someone turns on another tap in the house or flushes the toilet, the temperature of your shower will remain the same).

How should I calculate my hot water demand?

Calculating the hot water demand for any given application is usually done by adding the quantities of water consumed simultaneously. The critical demand is generally known as the peak flow, which means the demand that occurs during the first 10 minutes. It is also common to check the peak demand over the first hour and the continuous demand (per hour).

What option should I choose if there is no chimney?

Also known as a sealed boiler, the balanced flue boiler enables you to operate without a chimney, either in a residence with no chimney (new construction) or in one with a decommissioned chimney (renovation). Piping for flue gas discharge and fresh air intake comprises either a double concentric pipe of about 12 cm in diameter (for the most common residential boilers) or two separate pipes (one for fresh air, the other for combustion gases). The external connection to the balanced flue is either on an exterior wall or through the roof.
