Energy expert shares best temperature to avoid mould and reduce heating bills

Heating the home can be a struggle in winter as households will be keen to avoid mould growth but also want to reduce their energy bills as much as possible.

Amid rising energy bills and colder temperatures, it may seem harder to keep mould at bay.

However, one of the most effective preventative measures is the use of ventilation and heating.

So what temperature should a house be to avoid mould? According to the experts at Your NRG, it’s lower than what most would think.

They advised: “Keep your home’s thermostat over 14 degrees Celsius to prevent mould growth – a little higher in tiled rooms.

“Anything below this threshold will encourage damp to develop in your house, impacting your property and your well-being.”

However, it doesn’t mean that households have to leave their heating on all day to prevent the growth of mould.

The experts claimed that for “optimal efficiency and mould prevention”, households need to set their boiler to activate only when warm water or heating is needed and adjust to maintain the temperature they want.

This small adjustment can lead to “significant savings” on bills, claimed the energy specialists.

Even by simply lowering your thermostat by one degree, households could save over £100 annually.

For a comfortable and energy-efficient winter, households should aim to keep their room temperature between 18 and 20 degrees Celsius.

They said: “This range provides the ideal balance for both well-being and cost-effective heating.”

Households should also aim to get the best from their radiators when the heating is on. Most radiators have controls on the side to change the temperature. If used correctly, these thermostatic radiator valves – often numbered one to five (sometimes up to six) – can save them money. Experts recommend setting them at three or four to start with.

Bleeding your radiators can also save money by removing air bubbles which make it slower to heat up the home. Aim to bleed radiators every year as it starts to get cold.
