When the heating fails in Bath, hard water is usually behind it - Mendip-fed supply scales the heat exchanger until the combi kettles, and a scaled relief valve drops the pressure. In the tall split Georgian townhouses one boiler often feeds several storeys, so a weak pump leaves the upper rooms cold. A Gas Safe engineer who knows the city's water and housing gets to the cause faster.
Bath is built from honey-coloured Georgian stone terraces, much of it listed and within a World Heritage conservation city. Steep hills, spring-fed ground water and hard Mendip supply shape the work here, with consent constraints on almost every external repair.
Enter your postcode and EmergencyLines finds the nearest available heating engineer to you - day or night, weekends and bank holidays included. You get a number, you call it, and you speak to the heating engineer directly. No call centre, no middleman, no waiting on hold.
Bath's water is very hard (around 280 mg/l), so limescale risk to boilers and cylinders is high - scale on the heat exchanger is a leading cause of "kettling", lockouts and weak hot water here. With 28 air-frost days a year, a cold snap is when a struggling boiler finally locks out.
Sources: Water-supply hardness by postcode area (mg/l CaCO₃), UK water companies; Open-Meteo ERA5 reanalysis, 2015-2024 daily means (air-frost days & annual rainfall); Build-era profile derived from local housing stock; Principal water supplier, gas distribution network and electricity DNO by postcode area.
A quick steer before you decide - your Bath engineer confirms it on the day.
Bath sits on very hard water (≈280 mg/l), so scale on the heat exchanger shortens boiler life here - worth weighing in the call, along with a scale reducer on any new install.
These are the heating callouts we see most across Bath, shaped by the local housing and weather:
Combi boiler kettling on hard water and no heat across a multi-storey converted townhouse come up again and again here - usually down to the age and style of Bath's housing. Whatever the cause, the priority is the same: a verified heating engineer covering Lansdown, Combe Down and the rest of the city can make it safe quickly and tell you the cost before any work begins.
Pick what's happening and we'll give you the likely cause and the safe first step - then enter your postcode to reach a verified Bath heating engineer.
Likely cause: Often a diverter valve, a boiler fault or low pressure rather than the whole boiler.
Do this now: Check the pressure gauge reads about 1-1.5 bar and the gas and power are on, then call a Gas Safe engineer.
Likely cause: Usually a pump, motorised valve or thermostat fault - not a dead boiler.
Do this now: Try bleeding the radiators and check the thermostat is calling for heat; book an engineer if not.
Likely cause: The boiler has locked out to keep itself safe.
Do this now: Note the fault code, reset once, and if it locks out again leave it and call a Gas Safe engineer.
Likely cause: A leak on the system or a failed valve is dropping the pressure.
Do this now: If you can see water, turn the boiler off; an engineer should find the leak before topping up repeatedly.
Likely cause: Air, sludge or - in hard-water areas - limescale on the heat exchanger.
Do this now: Bleed the radiators; persistent noise or cold spots usually need a flush or descale.

In Bath, combi boiler kettling on hard water and no heat across a multi-storey converted townhouse top the list - often down to the city's older housing stock. Describe what's happening on the call and your heating engineer arrives prepared.
Yes - a boiler breakdown is the most common heating emergency in Bath. Enter your postcode and you'll see Gas Safe registered engineers available right now, day or night. You call directly, describe the fault or lockout code, and agree timing and price before any work starts.
Treat it as an emergency. Call the National Gas Emergency Service on 0800 111 999 straight away - it's free, answered 24/7, and the same number wherever you are. Open doors and windows, turn the gas off at the meter if you can, and don't touch light switches, electrics or naked flames until it's made safe. In Bath the gas mains are maintained by Wales & West Utilities, who attend the emergency; a Gas Safe registered engineer then repairs the actual fault on your appliance or pipework once the supply is confirmed safe.
No - it costs nothing to enquire. You only pay once you've spoken to the heating engineer, agreed the work and it's complete. There's no charge just to find out who's available near you in Bath.
That noise is almost always limescale. Bath's hard Mendip-fed water furs up the boiler's heat exchanger, and as the scale builds the water boils unevenly against it and bangs - the kettling sound. An engineer can flush the system, treat or replace the exchanger and fit a scale reducer on the incoming supply, which protects the boiler and quietens it for the long term.
Yes. Shared and landlord-owned systems are normal across Bath's split Georgian houses. The engineer isolates safely, gets heat back where possible and documents anything the freeholder or other flats must fix. In a tall townhouse one boiler often feeds several storeys, so don't sit cold waiting for a managing agent - get an engineer to make it safe and warm first.
