NW Heating Services provides the specialist Pool Boilers service for owners and organisations that need swimming-pool heating investigated, maintained or planned properly. The service begins with the pool duty and plant information rather than assuming that every loss of temperature needs the same answer.
Use repairs when the boiler has locked out, will not ignite or behaves unpredictably. Use servicing when planned appliance checks are due, and maintenance when a site needs an ongoing record of condition and priorities. Installation and upgrade pages help when the existing system is obsolete, poorly matched or no longer reliable. Residential and commercial pages explain the different information that helps each type of enquiry.

Explore service →The boiler creates heat, but controls decide when it runs, pumps move water and heat exchangers transfer energy into the pool circuit. Heat loss, operating schedules and pool covers also affect the outcome. NW Heating Services therefore asks for symptoms, temperature behaviour, equipment details and site constraints before confirming the appropriate scope.
Send the manufacturer and model, rated input where visible, fuel, indoor or outdoor setting, pool size or approximate volume, current and target temperature, fault codes, recent work and safe access arrangements. Commercial operators should also include opening hours, duty patterns and the operational consequence of downtime.
Pool Boilers is a service of NW Heating Services. The attending engineer’s competence and appliance categories are confirmed for regulated work. Water treatment and pool-side equipment may sometimes need a separate pool-maintenance specialist; the agreed boiler and heating-side scope is made clear before work proceeds.
