Frequently Asked Questions About Heating Engineer

Why are my radiators cold at the bottom?

Cold radiators at the bottom usually indicate magnetite sludge built up in the system. A power flush removes this sludge and restores full heat output.

How much does a power flush cost?

Power flush costs typically range from £300–£600 depending on the number of radiators. It is one of the most cost-effective heating improvements available.

Can I add a radiator to my existing central heating system?

In most cases, yes. A heating engineer will check system capacity, run new pipework, and install the radiator — usually within half a day.

Is a smart thermostat worth it?

Smart thermostats like Hive or Nest typically save households £100–£200 per year on heating bills. Installation takes 1–2 hours and they pay for themselves within 1–2 years.
