How to prevent frozen pipes in an empty house

In the mountains, a house left without heating for weeks in winter risks frozen pipes. Prevention is simple if you know what's happening at home.

The risk

When water freezes it expands and can burst pipes. The problem is often only discovered during the thaw, with a leak that may have run for days.

1. A minimum temperature, not a warm house

Thermostats and home automation systems have a frost protection mode that holds a minimum protective temperature without heating the house unnecessarily.

2. Sensors where the risk is

Place temperature sensors in the most exposed areas: garage, basement, boiler room, north-facing bathroom or loft.

3. Know if the heating stops

The problem isn't just the cold, but the boiler or heat pump stopping. A low-temperature, power-cut or fault alert lets you act in time. With oil-fired heating, the tank level can be monitored too.

4. Act remotely

From your phone you can raise the setpoint, check the temperature recovers and, if needed, alert a trusted person.

5. Water: the last line of defence

Flood sensors and a solenoid valve that shuts off the water if a leak is detected limit the damage if something fails.
