What’s involved
No hands-on steps here: what the job is, what a pro does, and what to have ready.
A box that takes hot water from a network outside your home and passes its heat to your heating and taps. There's no flame inside.
Its screen or gauges show the water's heat coming in and going out, its pressure, and the heat you've used. A warning light means it needs a look.
Usually the heat network or the building owns the unit and its meter. A sticker on it, or the bill, says who to call.
They read the fault, check its valves and strainers, and set it up again. Its cover stays on for everyone else.
Photograph the display, any warning, and the sticker with the unit's number and the network's phone.
No heat or hot water, a warning light, water dripping, or the pressure out of range: call the number on the unit.
Don't open the unit or turn its valves: the water inside is very hot and under pressure.
What you need
- Your phone, for photos
