No Hot Water in Birmingham? Common Causes & How to Fix It
Hot water repair Birmingham
There’s nothing worse than turning on your hot tap or shower and being met with freezing cold water. If you’re experiencing no hot water in Birmingham, don’t panic – it’s a problem our team at Afterglow Plumbing & Heating deal with daily across the city.
Whether you live in a modern apartment near Birmingham City Centre, in a townhouse around Edgbaston, or a family home in Solihull, hot water problems can happen to anyone. Below, we’ll look at the most common causes and how they can be fixed.
Hot Water Problems with Combi Boilers
Combi boilers are popular in Birmingham apartments and smaller homes, especially around areas like Digbeth and the Jewellery Quarter. But when they go wrong, you can quickly end up with no hot water at all.
Typical issues include:
- Blocked plate heat exchangers – limescale or sludge build-up can prevent the boiler from transferring heat effectively, leaving you with lukewarm or cold water.
- Faulty diverter valves – this valve switches the boiler between heating your radiators and heating your hot water. When it sticks or fails, you might find your central heating works fine but the hot taps don’t.
If your combi boiler is leaving you without hot water, it’s time to call in the experts. We provide fast, reliable boiler repair in Birmingham to get things flowing again.
Hot Water Cylinder Problems
In larger houses around Harborne, Moseley, and Sutton Coldfield, it’s common to find unvented or open vented hot water cylinders. These can also develop faults that leave you with no hot water, such as:
- Faulty immersion elements – these electric heaters can burn out, meaning the cylinder no longer heats up.
- Overheat thermostats – when these trip or fail, the cylinder may stop producing hot water altogether.
- Faulty two-port or three-port valves – if these stick, the hot water simply won’t flow where it’s needed.
We regularly replace and repair hot water cylinders in Birmingham apartments and houses. Find out more about our hot water cylinder installation and repair service.
Faulty Taps & Fluctuating Hot Water
Sometimes the problem isn’t the boiler or cylinder – it’s the taps themselves. Faulty cartridges, washers, or mixer taps can restrict hot water flow completely.
Other times, you may notice your hot water runs hot and cold. This is often linked back to your combi boiler, where inconsistent performance or a diverter valve issue can cause sudden changes in temperature.
Low Hot Water Pressure
Another common issue we see across Birmingham homes is low water pressure from the hot tap. This can be caused by:
- Blocked pipework
- Old gravity-fed systems with a small combination tank that doesn’t sit high enough above the taps
In situations like this, one solution is replacing the combination tank with a thermal store. A thermal store provides mains pressure hot water, improving flow rates significantly – particularly useful in homes where showers and baths feel weak. (We’ll be covering thermal stores in more detail in an upcoming blog).

If your hot water cuts out suddenly – whether in the middle of a morning shower in a city-centre flat or late at night in a suburban home – you may need an emergency plumber in Birmingham. Our team is available when you need us most. Find out more about our emergency plumbing services.

Frequently Asked Questions – No Hot Water in Birmingham
1. Why is my combi boiler not giving me hot water?
Combi boilers often stop producing hot water due to a faulty diverter valve, a blocked plate heat exchanger, or low water pressure. If your heating works but you’re not getting hot water, it’s usually a diverter valve issue. You’ll need a professional boiler repair in Birmingham.
2. Why do I have heating but no hot water?
This usually points to a problem with the diverter valve in a combi boiler or a motorised valve in a system with a hot water cylinder. It tells your boiler where to send the hot water – if it sticks, you’ll get heating but no hot water.
3. Why is my hot water running hot and cold?
If your taps or shower are fluctuating between hot and cold, it could be an issue with your combi boiler’s flow sensor, temperature sensor, or diverter valve. Sometimes faulty mixer taps can also cause this problem.
4. Why do I only get hot water from my immersion heater?
This often happens when the boiler has stopped heating the cylinder, leaving the immersion as the only heat source. The problem may be with the boiler itself, a faulty programmer, or a broken two-port/three-port valve.
5. Why is my hot water pressure so low?
Low hot water pressure can be caused by:
- Blocked pipes
- A gravity-fed system with a small tank in the loft
- Scale build-up in the hot water cylinder
In homes with old gravity-fed systems, upgrading to a thermal store can boost hot water performance significantly.
6. Can faulty taps stop hot water from working?
Yes – if the cartridge or internal parts of your mixer tap fail, you may get little to no hot water through that outlet. This can sometimes be mistaken for a boiler fault.
7. Do I need an emergency plumber if I have no hot water?
If your hot water cuts out suddenly and you can’t manage without it – for example, in a flat in Birmingham City Centre – then calling an emergency plumber in Birmingham is the fastest way to get it fixed.
8. How long does it take to fix a hot water cylinder?
Repairs can often be done in a single visit, depending on the fault. A simple immersion element replacement can take an hour, whereas a full hot water cylinder installation or repair may take longer.
