    Warm Air

    At Plumbusters we understand that many property owners are looking for highly-efficient ways to heat their home and provide hot water. Alongside our traditional boiler services and systems we also offer services for warm air heating. We’re proud to be recommended by Johnson & Starley, a leading manufacturer of warm air heating systems.

    Warm Air Heating Benefits

    Condensing warm air heaters offer many different energy saving features whilst also being able to provide traditional heating services such as radiators and domestic hot water. We are able to offer a range of options when it comes to maintaining and servicing an existing warm air heater. We can also offer upgrades to existing boilers that can incorporate Up-flow and Down-flow warm air heaters. Our warm air heating systems can also provide cool air too – perfect for hotter days!

    Johnson & Starley have been making warm air heating systems since 1922 – proper heritage in the UK market!
    Rapid heat-up times mean the house warms up quickly – no waiting around on a chilly morning
    No bulky radiators means more flexible room layouts and easier furniture placement.
    Low maintenance once installed properly, and many older J&S units are still going strong after 50+ years.
    These units can reach up to 98% thermal efficiency, which is brilliant for cutting gas bills.
    The Aquair Heat Interface Unit (HIU) lets you keep the existing warm air ducting but connects to modern heat sources like combi boilers, ASHPs, electric boilers.
    Aquair is super versatile and future-proofs the system (especially handy for going greener without ripping out all the ducts).
    You can save over 28% on fuel compared to older non-condensing models.

    We primarily maintain and install Johnson & Starley warm air unit heating systems but if you use an alternative warm air system and need some assistance please do feel free to contact us!

    Frequently Asked Questions

    What is a warm air heating system, and how does a Johnson & Starley unit work?

    It circulates heated air via ducts for even warmth. WarmCair models draw cool air, heat it over an exchanger, and fan it out quickly, ideal for UK homes without radiators.

    How often should I service my Johnson & Starley warm air heater?

    Service annually by a Gas Safe engineer for safety and efficiency. This maintains warranties (2-5 years) and prevents breakdowns in UK installations.

    Can I install a smart thermostat with my Johnson & Starley system?

    Yes, if volt-free or OpenTherm compatible like for WarmCair. Use matching controls to avoid issues; consult a Gas Safe pro for UK regs compliance.

    What should I do if my Johnson & Starley warm air unit breaks down?

    Check power, thermostat, pilot light, and filters. For Economaire, note LED codes; WarmCair, try reset. Please contact us is unresolved and we will be more than happy to come and sort this for you.

    How can I upgrade or replace an old Johnson & Starley warm air heater?

    Switch to WarmCair (up to 98% efficient) or Aquair with heat pumps. May qualify for UK grants like Boiler Upgrade Scheme; use MCS installer.

    Why is my Johnson & Starley system losing pressure, and how do I fix it?

    Often due to leaks; check pipes and top up to 1-1.5 bar via filling loop. Persistent drops need a Gas Safe engineer to repair for efficiency.
