Regular conservatory users
If you spend extended periods in the room, maintaining its air temperature may matter more than warming one seat. Compare thermostats and timers on convection models, while allowing for clear airflow around the heater.
Who is the heater for?
Occasional users seated near cold glazing
If visits are short and you usually sit in one area, consider whether an infrared panel can be positioned for that area. Herschel positions fast-warming infrared models for occasional conservatory use; check its sizing and mounting instructions for your room.
Households dealing with condensation
If cold walls also show condensation, mould or persistent damp, investigate ventilation and the condition of the building alongside heating. Government ventilation guidance explains that moisture can condense on cold walls when ventilation is ineffective.
What matters when choosing?
Decide whether you need warmth across the room or mainly where you sit, then check how glazing, draughts and your pattern of use affect the choice.
| Concern | What to check | Who this matters to |
|---|---|---|
| Comfort beside cold surfaces | Map the seating area and cold glazing. Check whether an infrared panel can be sized and mounted to serve that area. | When I sit beside cold glazing, I want warmth where I sit, not only warmer room air; around 42% of consumers would make targeted comfort their primary concern. |
| Whole-room temperature | Assess glazing, draughts and wall heat loss as well as the supplier's sizing guidance. Check for a thermostat and a timer. | If I use the conservatory for long periods, I need the room air held at a usable temperature; roughly 33% of consumers would prioritise whole-room temperature control. |
| Heating only when needed | Check timer settings and any open-window function on the exact model. Confirm whether app control needs additional equipment. | When my visits are irregular, I do not want the heater running to an unsuitable schedule; about 25% of consumers would put avoiding unnecessary operation first. |
Buying pitfalls
-
Sizing by floor area alone
Glazing, draughts, ceiling height and cold walls affect a conservatory's heat loss. A supplier's room-size figure for a particular model is a starting point, not a room-specific assessment.
Measure the space and note its glazing and draughts. For a heavily glazed or persistently cold room, seek a room heat-loss assessment before choosing an output.
-
Expecting a heater to fix damp
Government ventilation guidance links trapped moisture with condensation on cold walls. Extra heating does not identify a leak or correct ineffective ventilation.
Check condensation patterns, staining, leaks and ventilation; arrange appropriate building checks or repairs rather than relying on heater output to mask persistent symptoms.
-
Overlooking power supply and clearance
Electrical Safety First warns that high-powered appliances such as heaters can overload sockets or extension leads. Heater vents and required clearances also need to remain unobstructed.
Plan a suitable supply and follow the chosen model's installation and clearance instructions. Do not daisy-chain extension leads.
If there is no suitable supply at the intended position, arranging electrical work may be necessary.
-
Treating smart controls as a cure for heat loss
A timer or open-window function can change when a heater runs, but it cannot insulate glazing or stop a draught. Dimplex and Devola describe these controls on specific models, not every panel heater.
Choose controls you will use, and assess draughts and cold surfaces separately.
Relevant brands to compare
Dimplex
Its PLXE range is an installed convection-panel option for buyers seeking electronic time and temperature control.
- Dimplex UK lists adaptive start and open-window detection for the PLXE range.
- App control requires an RF module and Dimplex Control Hub; check the intended model's output against the conservatory's heat demand.
Devola
The DVPW2000WH is a glass-panel convection model with wall-mounted or freestanding installation options.
- Devola lists a thermostat, 24-hour/7-day timer, three power settings and open-window detection for the DVPW2000WH.
- Devola's room-size claim for this model should not replace an assessment of a heavily glazed or draughty conservatory.
Herschel
Its infrared range offers a route to compare when warmth is needed in a defined area or ceiling mounting is being considered.
- Herschel recommends fast-warming models for occasional conservatory use and slim panels for continuously used conservatories with suitable glazing and building specifications.
- Check placement and sizing rather than assuming a particular effect on condensation or running costs from the heating method alone.

Questions about conservatory heating
Should I choose a convection or infrared panel for my conservatory?
Choose convection if maintaining room-air temperature during regular use is your main aim; consider infrared if you use a defined seating area for shorter periods. For infrared, check the panel's sizing and mounting guidance rather than assuming lower running costs.
Will a panel heater fix cold walls or condensation?
No: heating can improve warmth but does not repair the cause of a cold wall or persistent moisture. Government ventilation guidance notes that trapped moisture can condense on cold walls, so check ventilation and possible leaks or building defects alongside heating.
Can I use an extension lead for a high-powered panel heater?
Plan for a suitable socket rather than relying on an extension lead. Electrical Safety First warns against overloading sockets and extension leads with high-powered appliances such as heaters; do not daisy-chain leads, and check the heater's installation instructions.
