Do You Have a Myson Boiler or a Myson Radiator?

Myson is unusual because the brand has been used for both boilers and heating emitters. The quickest way to tell:

• Boiler: a wall-hung box (often in a kitchen/utility cupboard) with a flue and gas pipe, plus a model data plate and controls.
• Radiator / emitter: a steel panel radiator on the wall, a fan convector, or a kickspace heater (under-cabinet unit). Myson branding is often on an end cap, grille, or label.

Myson boiler models you may see referenced include:

• Myson Apollo
• Myson Midas
• Myson Marathon
• Myson Economist
• Myson Velaire

If your search is “Myson boiler repair”, it’s usually one of the older boiler models. The honest reality is below.

The Reality About Myson Boilers

Myson boilers have been discontinued for many years. If you still have a Myson boiler in London, it’s typically well beyond its expected service life.

• Parts availability: many Myson boiler parts are now difficult to source. Some generic components may be possible, but brand-specific parts are often unavailable.
• Age: surviving units are commonly 15-25+ years old (sometimes older depending on model and upkeep).
• Reliability: once one component fails on a boiler of this age, further faults are common.
• Efficiency: older non-condensing boilers are typically less efficient than modern condensing boilers (real-world performance varies by system condition and controls).

Our honest view: if a Myson boiler has failed, replacement is usually the most practical, cost-controlled route in London.

Quick Checks (60 Seconds)

Before assuming the worst, a few basic checks can save a call-out:

1. Check power: confirm the fused spur is on and your fuse box hasn’t tripped.
2. Check thermostat/programmer: after a power cut, timers can reset. Replace batteries in wireless controls.
3. Check system pressure (sealed systems): if the gauge is low, follow our pressure guide.
4. Check gas supply: do other gas appliances work (hob/cooker)? If not, it may be a supply issue.
5. Reset once only: if it locks out again after one reset, stop and book an engineer.

Common Myson Boiler Problems

Typical faults we see on aging Myson boilers:

• Ignition failure: electrodes, ignition leads, or control faults.
• No hot water: diverter valve or heat exchanger problems (where fitted).
• Leaking: corroded components, seals, valves, or pump issues.
• Cutting out: overheating from poor circulation, sludge, or component wear.
• Strange noises: kettling, banging, or gurgling from limescale, sludge, or trapped air.
• Pilot/keep-lit issues: thermocouple or gas valve problems on older designs.

What We Check on Arrival

If we attend a Myson boiler, our Gas Safe engineer will typically:

• Confirm the exact model and approximate age from the data plate
• Inspect for leaks, corrosion, scorching, and any flue/ventilation concerns
• Check system pressure, pump operation, and heating controls
• Run safe operation checks where appropriate
• Assess whether compatible parts are realistically available
• Give a clear recommendation: repair viability vs replacement economics

Repair vs Replace: The Practical View

With discontinued boilers, the decision usually comes down to parts, repeat-fault risk, and total cost.

Example repair scenario (illustration only): call-out, diagnosis, and repair could cost £350-500+ depending on the fault and whether parts can be sourced.

• Brand-specific parts may be unavailable.
• Even after a repair, other age-related failures are common.
• Repairs on legacy equipment typically come with limited reassurance compared with a new-install warranty.

Compare that to replacement: a new boiler from £1,899 gives you warranty-backed support and a predictable long-term outcome.

Myson Radiators, Fan Convectors, or Kickspace Heaters

If your Myson-branded item is an emitter (radiator/fan convector/kickspace heater), the fix is often system-side rather than “boiler brand” related.

Common radiator and emitter problems:

• Cold at the top: trapped air (often needs bleeding).
• Cold at the bottom: sludge restricting flow (may need a power flush).
• Some rooms hot, others cold: balancing or circulation issues.
• Leaking: valve or connection issues; corrosion can mean replacement.
• Fan convector not working: power spur/fuse, thermostat setting, fan motor, or wiring fault.
• Kickspace heater issues: power supply, fan obstruction/dust, control fault, or low flow through the coil.

Quick checks for fan convectors / kickspace heaters:

1. Check power: is the fused spur on (often above the unit or in a nearby cupboard)?
2. Check controls: thermostat turned up and heating “on”.
3. Check airflow: grilles clear of dust and obstructions.
4. If it still won’t run: book an engineer (electrical faults should be checked safely).

What Happens When You Call Us

Here’s our approach to Myson enquiries:

1. We identify what you have: Myson boiler or Myson heating emitters.
2. We understand the symptoms: no heat, no hot water, cold radiators, leaks, noises, fault codes.
3. We give honest advice: if it’s an obsolete boiler, we’ll be clear about repair reality.
4. We provide options: repair (where viable) or a clear, fixed-price quote for replacement/upgrade.
5. You decide: no pressure, just practical guidance.

Landlords: Legacy Myson Boilers Are a Risk

If you manage a rental with a Myson boiler (or aging Myson emitters), planned upgrades usually beat emergency call-outs:

• Tenant satisfaction: breakdowns cause complaints, void periods, and emergency costs.
• Predictable spend: planned replacement is often cheaper than repeated repairs on legacy kit.
• Compliance confidence: modern boilers are simpler to maintain and certify.
• System performance: we can also address radiator/emitters, balancing, and sludge issues to reduce future faults.

We support landlords across London with Gas Safety Certificates (CP12) and planned heating upgrades. See our London landlord checklist.
