    What Boiler Brands Do We Repair?

    Combi Boiler Repair In Grays

    Thames Boilers provides top-notch repair services for combi boilers – highly favoured by Grays homeowners due to their compact footprint and impressive energy efficiency.

    Common problems that we deal with include:

    • Stuck diverter valves
    • Pressure relief valve failures leading to boiler pressure dilemmas
    • Condensate pipe complications, especially when Jack Frost visits and the pipe can freeze, causing the boiler to call it a day.

    Our Grays-based engineers excel at detecting and rectifying these niggles swiftly, meaning your combi boiler will be steaming away again in no time.

    Vaillant Boiler Repair

    Boilers from the prestigious Vaillant brand are known for top-tier quality. Nonetheless, even the best boilers can run into some setbacks over time. You might have come across issues like the lack of hot water or error codes like F75, F22, or F62. At Thames Boilers, we’re seasoned veterans when it comes to sorting out these boiler-related glitches.

    Ideal Boiler Repair In Grays

    Ideal Boilers are a common sight in UK homes due to their trustworthy operation and economical performance. But, like all appliances, they might sometimes face issues – for instance, problems with the printed circuit boards or the L1 and L2 fault codes. At Thames Boilers, we’ve got you covered. Our repair service handles these glitches and much more. Plus, we provide a routine boiler check-up at no extra cost (worth £96) with all our set-price Ideal Boiler repairs.

    Worcester Bosch Boiler Repair

    Worcester Bosch holds a prestigious place in the world of boiler makers due to their sturdy nature. That said, every appliance has a lifespan and problems may arise such as obstructions in condensate traps, faulty circuit boards or issues with ignition. Luckily, our technicians in Grays are more than equipped to handle such challenges, offering a service that is both smooth and affordable. Indeed, there’s a whole year’s guarantee on any new components we install during the repair process, assuring your comfort and tranquility.

    Baxi Boiler Repair

    Baxi boilers often stand out for their long-lasting service and excellent performance. Usual disruptions we can handle include problems related to auto-air vents that fail to function properly leading to pressure glitches, temperamental diverter valves or a congested condensate pipe, especially when it’s chilly outside. Trust our capable engineers in Grays, who have a rich experience in diagnosing and repairing Baxi boiler issues. We practise a reasonable fee policy: If we can’t repair it, you only pay a small fee.

    Potterton Boiler Repair

    While Potterton boilers are well-regarded in UK households, there can be ordinary issues like a problematic fan assembly or a glitchy printed circuit board. The specialized engineers at Thames Boilers are adept in addressing these repairs with exactness. On top of this, all replaced parts are backed by a 1-year guarantee, and if we can’t sort your Potterton boiler, a modest fee will apply for the engineer’s visit.

    Boiler Repair Questions & Answers

    How soon can you fix my boiler?

    This is usually determined by the time of year and prevailing weather conditions.

    In the warmer months, we usually have availability on either the same or following day, assuming it’s a weekday.

    In contrast, during the cold times of the year, securing an appointment can take somewhat longer because of the increased workload. We regret any inconvenience this may cause.

    Can you fix my type of boiler?

    We are capable of repairing all types of boilers, although we do not deal with oil boilers, LPG boilers, boilers over 70kW or those classified as beyond the threshold of economical repair. Anything else, we’re here to mend it for you. Do note, certain boilers may not be applicable for our fixed price repair scheme and will be billed based on the number of hours worked and materials utilised.

    Do I have to pay a callout fee?

    No callout fee will apply if your boiler is applicable for a fixed fee boiler repair.

    However, if your boiler is not applicable for a fixed fee boiler repair, a minimum charge of 1 hour’s labour will apply for an engineer’s visit.

    What if I need a new boiler?

    Sometimes, it comes to pass that fixing a boiler may not be the most economical choice. That could be down to a missing part that is hard to find or when repair costs start nearing that of a new boiler. When such a situation occurs, we ensure to let you know pronto and help you understand why a new boiler is the better option. We’ll present a clear and detailed quote for a new boiler, and then leave the ball in your court to decide your next step. If you do select us to replace your boiler, we will endeavour to put you on top of our list so your new boiler is fitted as quickly as possible, usually within 48 hours.

    Boiler Servicing Questions & Answers

    Will servicing my boiler fix any faults or problems?

    This is a usual misconception. A boiler service is all about making sure your boiler is safe and executing regular maintenance duties. If there are issues with your boiler, a service won’t solve them.

    We would suggest you reach out to us to confirm your fixed price boiler repair beforehand. Then, after the issue has been mended, you can go ahead and book your boiler in for a service.

    Do I Need To Turn My Boiler Off Before It’s Serviced?

    Yes, if you can be without your boiler for a while, please turn the boiler off about 30 minutes before we arrive. This gives the boiler chance to cool down, ready for our performance tests.

    How Do I Check My Boiler Has Been Serviced Properly?

    The following tips can help you ascertain if your boiler has been attended to appropriately:

    1. Once your engineer is done with the service, a service certificate should be issued to you. This would either be electronically via email or as a physical paper certificate and should carry all details regarding the checks done on your boiler.
    2. A typical boiler servicing should take about 30 – 45 minutes for standard service and somewhere between one to one and a half hours for a complete service. If you find your service was completed in less time than this, it’s possible that it wasn’t done thoroughly.
