Do you provide free quotations?

For larger projects such as a bathroom refurbishment, boiler & central heating installations, we will send our surveyor out to discuss your project and provide you with a free no obligation quotation.

 

Are you Gas Safe / Corgi Registered?

All our engineers have the relevant qualifications to carry out the works, including Gas Safe. We will never send an unqualified person to carry out work.

 

How often should my boiler be serviced?

All gas appliances should be serviced/safety checked at least every 12 months. This is especially important in gas boilers. Servicing will inevitably prolong the life of your appliance and prevent issues arising.

 

What is a magnetic system filter?

System filters are fitted on the last part of your heating system, before the water returns to the boiler. The filter is designed to catch particles & sludge from your system, in the filter, before it returns into the boiler. System filters are cleaned out during a routine boiler service.

 

What pressure should my boiler be on?

Between 1 and 1.5 bar is ideal. There will be a filling loop to re-pressurise the boiler should it be low. Don't worry if it's above this, there will be a pressure relief valve to release excess water. Alternatively you can vent a radiator to reduce the pressure.

 

Why is my radiator cold at the top, but hot at the bottom?

This usually means there is air trapped at the top of the radiator. Air can be released from a radiator with the use of a vent key on the vent pin, which is located at the top on the left or right side of the radiator.

 

Why is my radiator hot at the top, but cold at the bottom?

The most common cause of this is sludge build up in the radiator. This can be rectified by having a Power Flush.

 

What is a power flush?

A power flush is the process where a low pressure but high water flow pump is connected to the central heating system, and pumps water through at a high velocity. With the combination of the necessary chemicals, this will break up and dislodge any material, limescale or black sludge build up and will leave your system working at 100% efficiency.

 

Do I need a power flush?

If your central heating system has been under performing, your radiators are taking longer to warm up, or you are noticing cold spots on them, your system may benefit from a powerflush. Contact us to discuss your system and we will advise on the best solution.

 

Will a power flush make my system more efficient?

Poor water flow, blockages and cold spots can all cause your central heating to take longer to warm up, and it will also have to work harder to keep your home warm and at a constant temperature. The harder it has to work, the more fuel it will consume and the more money it will cost to maintain. After power flushing your central heating system, your system will become much more efficient, and require less energy and fuel to keep a constant temperature in your home.
