Reasons your system might need a power flush

Cold luke warm radiators

are one of the symptoms that you have a problem with your central heating system and a professional powerflush off your central heating system will solve this problem. We use the latest Kamco professional equipment and are fully trained.

Slow heating response

is one of the symptoms you need a powerflush on your central heating system, this is usually spotted when radiators take a long period of time to heat up or you don’t get the heat out of them required, call us for free advice.

Pump noises

If you are hearing strange noises coming from your central heating pump, surges grating then this is a clear sign that your pump is struggling and becoming blocked with sludge then a powerflush is wise and can save the cost of replacing the pump.

Boiler noises

One of the signs that sludge and debris is building up is weird noises coming from the boiler, bangs and sudden surges can be heard if so then an inspection and powerflush of the system will solve this and be cheaper than a new boiler!

Poor hot water

If you are finding that when you turn the tap on fully it’s running cold for a long period of time or goes cold when fully open then a powerflush is of benefit as this is a sign that the boiler is having a problem creating hot water.

Poor circulation

Another common problem is the central heating system pipes get clogged up with sludge and debris.Below is a more detailed diagram showing symptoms which indicate a central heating system that can benefit from a power flush, were all for educating our clients so they know what they should look for.

I would highly recommend Leinster Gas. My gas boiler packed in and Jamie installed a new one within two days after making the phone call. I could not find any faults with Leinster Gas they are the most professional company to deal with and with definitely be using them in the future and will be recommending them to my friends and family. Thanks Jamie.👍

Absolutely fantastic company to deal with. Had new boiler installed on Friday and Jamie and the other lad did a brilliant job; so clean and tidy and the house has never been warmer. Would recommend Leinster Gas to anyone 💯 thank you 😊

I used Leinster today for a full flush, change 3 valves, change 3 radiator thermostats and balance the whole system. Very professional, very quick and great value. Jamie is great to deal with and Luke is nice also. Left the house the way they found it. I have been really messed about with other plumbers but delighted with Jamie and Leinster gas. Highly recommend and will be my go to plumber from now on. Great service.

Jamie and Victor installed my new boiler and removed an old back boiler. They are absolute professionals at what they do. I cannot recommend them highly enough. Great communicators and extremely hard working. Jamie figured out the best option for me when assessing the replacement of an old back boiler with a new combi boiler. He was very patient and great at explaining the pros and cons of each option. Himself and Victor went above and beyond to make the new system work practically as well by considering the (inconvenient!) position of my gas cooker in the kitchen. There was an easier way of doing it but they went the extra mile to ensure that the kitchen functioned well with the gas cooker in it's current spot.. that meant extra inconvenient piping for them (I think!)Thanks so much to Jamie and to Victor and for sure give Leinster Gas a call if you need a job done efficiently and professionally.

I'd thoroughly recommend Leinster Gas. Jamie stepped through an overview of work involved in removing the old and installing the new heating system. The day of the installation, the team arrived on time, set out floor protectors and promptly got to work, and didn't seem to stop until everything was installed later that day. Great work, no stress, satisfied customer.

Leinster Gas were excellent to deal with and Jamie was very good at responding to any questions I had. We had a new boiler fitted and Jamie was very knowledgeable and easy to deal with when it came to deciding on a boiler and he provided detailed quotes which is not always the case when ringing around looking for a quote on a new boiler. Victor was spot on and got the job done efficiently and neatly with no fuss. Heating was blasting out of the radiators for the next week but as the warmer weather kicked in we used it less and some of the radiators stopped working properly when we turned them on. Jamie promptly advised me what to do and we got them working again.Overall they were very good to deal with and accommodating, even fitted us in at very short notice,good value too compared to a lot of the other boiler installation companies.
