When the heating struggles we look at the whole system, from the pump and valves to the radiators and controls. The photo shows a corroded pump and zone valve we found in an airing cupboard before replacing them.
Cold radiators
Trapped air, sludge or a sticking valve.
Sludge
Chemical clean or powerflush, then a filter and inhibitor.
Pumps
Noisy or seized pumps swapped out.
Zone valves
Hot water with no heating, or heating with no hot water.
Controls
Smart thermostats fitted and set up on your phone.
Noisy pipes
Banging, ticking and gurgling traced and quietened.

Questions
Why are my radiators cold at the bottom?
That's usually sludge. A flush and a magnetic filter sorts it.
Is a powerflush worth paying for?
For heavy sludge, yes. For light build-up a chemical clean may be enough.
Can you fit a smart thermostat?
Yes, and we'll set it up with you.
