Yes, heating alone will not remove moisture. Warm air holds more water vapour, but unless it is extracted it condenses on cold surfaces such as windows and outside walls. Building regulations generally expect mechanical extraction in bathrooms and shower rooms, so pair your heater or towel rail with a suitably rated extractor fan and check the current regulations for your area.

The most cost-effective option is usually a correctly sized heater with accurate electronic thermostat and timer control, so it only runs when the room is occupied. Panel heaters and electric radiators with eco modes suit rooms used regularly, while low-wattage tubular heaters or frost watchers are better for background protection. Running costs depend on your tariff, insulation and usage pattern.

Reduce condensation by removing moisture at source and keeping surfaces warm. Fit extractor fans in kitchens and bathrooms, ideally with timers or humidity sensing, consider positive input ventilation for whole-house air movement, and keep rooms at a steady background temperature rather than letting them go cold. Persistent mould may indicate a building defect that needs a survey.

Many can. Wi-Fi heaters such as the ATC Aeris ECO and iLifestyle ranges connect to an app for scheduling and remote temperature changes, and Wi-Fi thermostats can control underfloor heating. Standard heaters can also be switched remotely through a Wi-Fi fused spur, although the heater's own thermostat then remains the main temperature control.

Commercial sites typically use overdoor heaters at busy entrances, outdoor heaters for terraces and smoking areas, panel heaters for offices, under-sink water heaters for point-of-use hot water and high-speed hand dryers in washrooms. Extraction should be sized for the occupancy and use of each room, so check the building regulations that apply to the premises.

A rough guide is about 100W per square metre for a well-insulated room with a normal ceiling height, so a 15m² room would need around 1.5kW. Older or poorly insulated rooms, or those with high ceilings and large windows, need more. Many installers use an online heat-loss calculator for accuracy. Panel heaters with built-in thermostats help control running costs.

Bathroom extractor fans are usually chosen by extraction rate, measured in litres per second or cubic metres per hour. Building regulations in the UK set minimum rates for bathrooms and kitchens, and the fan must be suitable for the bathroom zone it is installed in. Timer and humidistat models keep running after the room is used to clear moisture. Check current regulations.

Positive input ventilation (PIV) units are usually fitted in the loft. They draw in fresh, filtered air and gently push it into the home, which displaces moist, stale air and helps reduce condensation and mould. PIV is a popular whole-house solution for existing homes with condensation problems. Follow the manufacturer's sizing and installation guidance.

Electric panel heaters convert almost all the electricity they use into heat, so running cost depends mainly on the electricity tariff, the heater size and how long it runs. Models with accurate electronic thermostats, timers and open-window detection avoid wasted energy. Heating only the rooms in use and good insulation make the biggest difference to running costs.
