Deciding between repairing or replacing your boiler hinges on several considerations, including the boiler’s age, the severity of gas and water leakages, and its overall efficiency. While repairing an aged swimming pool boiler might be financially sensible in certain instances, opting for a new swimming pool boiler installation could prove more advantageous in the long run, especially if the existing unit is approaching its service life’s end or is plagued by substantial issues or the prospect of recurring repairs. A brand-new boiler not only offers extended manufacturer warranties but also represents a sound investment towards future savings keeping your pool heated.

We work reputable pool boiler manufacturers to ensure the quality and reliability of your swimming pool boiler. For those looking to upgrade or install a new system, swimming pool boiler installation is an essential service to consider. Don’t forget the importance of regular swimming pool boiler servicing to keep your pool boiler in optimal condition.

We repair any gas swimming pool boilers domestic or commercial, we sadly don’t work oil swimming pool boilers.

Swimming pool boiler servicing can help the boiler’s energy efficiency but there are various energy-efficient heating options available for swimming pools. Solar panels, for instance, facilitate the heating of swimming pools by harnessing sunlight through a solar collector, subsequently transferring the heat to pool water circulated by a pump. While solar panels provide extended warranties, rapid return on investment, and substantial cost savings over the lifetime, their effectiveness may be diminished in colder climates where a pool heated by solar panels might not reach the desired temperature.

Another energy-efficient option is the use of a thermal pool blanket. This can significantly decrease swimming pool heating expenses, with potential savings ranging from 50% to 70%. This is achieved by mitigating water evaporation and dehumidification processes, as well as reducing heat loss by up to 80%.

Several common problems can affect the function of your swimming pool boiler. Some of the most frequently seen include:

• The boiler won’t ignite – this is a common issue. First, check whether the heater has been turned on and the temperature has been correctly set. The thermostat must be set at a higher temperature than the water temperature. Check that the filter and pump are clean, and that the pilot light is lit. If it isn’t, you should check the venting, air supply and gas pressure, and ensure the pilot tube isn’t clogged or damaged. Make sure that the gas supply valve has been turned to the on position too.
• Clogged filters and strainers
• Low gas pressure
• Mechanical failure
• Gas flow problems
• Closed gas line supply valves
• Obstructed gas lines
• Faulty flame sensors
• Low flow of water – for the pool boiler to operate efficiently and smoothly, the pool system has to maintain a consistent water flow. Pool boilers are fitted with a pressure sensor to detect and monitor any change in the water flow.
  Sometimes, the LCD screen of the boiler will show a warning of “Low Water Flow”. If this happens, the problem could be a dirty filter. If the filter pressure gauge’s PSI reading is too high, the filter needs cleaning. The problem could also be due to a dirty pump basket. Make sure any debris is removed and that the lid and basket are in good condition. If several water features are operating at the same time, this could be the reason for low water flow, but the most common cause of this problem is a defective pressure switch or sensor.
• The boiler keeps turning on and off – this could be a sign that the power supply or electrical connection is having issues, but there are a few other possible causes of this problem too. The pool water chemistry may be wrong, the pressure sensor, high limit switch or thermal regulator could be corroded, covered in scale or experiencing electrolysis issues. Also, if the filter is dirty, low pressure can be the result and this can cause the pressure switch of the heater to turn off. The heat exchanger may also have deteriorated, so it should be inspected for sanitizer or chemical damage.
• Dirty filters
• A clogged heat exchanger
• Insufficient gas flow
• The boiler isn’t heating up – sometimes, the boiler will ignite but fail to reach the selected temperature. Other times, the boiler won’t generate any heat at all. If this is the case for you, check that the temperature sensor isn’t damaged or installed incorrectly, and try setting the thermostat to a higher temperature. It’s also possible that the heater is the wrong size for your pool – oversizing the pool heater will shorten the amount of time needed to heat up your pool.

In numerous instances, our Gas Safe registered engineers can complete the swimming pool boiler repair and have it on the initial visit. We carry most Laars, Pentair, and Certikin boiler parts.

On occasion, some boilers might be beyond economical repair, such as the heat exchanger has split and is is not cost-effective, in which case our engineers will provide guidance on the most suitable course of action . We aim to keep you well-informed throughout the entire process.
