No Hot Water, Heating Works? Your Checks in Westhoughton

When your radiators are toasty warm, but the hot tap runs cold, it's a frustrating situation. Many customers in Westhoughton and the surrounding areas immediately think the boiler is broken. However, in this specific scenario, the boiler itself is usually fine. The issue typically lies with the component that directs the heat either to your radiators or to your hot water supply: the diverter valve. Before you pick up the phone, there are a few simple and safe checks you can carry out yourself.

Westhoughton FAQs — no hot water but heating works — safe first checks before you call

Can I fix a stuck diverter valve myself?+

No, diverter valve replacement or repair requires specialist tools and Gas Safe registration. Attempting this yourself is unsafe and can damage your boiler further, potentially voiding manufacturer warranty.

Is this issue expensive to fix?+

The cost depends on the specific part that has failed, whether it's the valve itself, the motor, or another component. We diagnose the issue accurately before recommending any repairs.

Does boiler age make this more likely?+

Components like diverter valves can wear out over time regardless of boiler age, though older boilers, especially in 1990s–2000s housing stock common around Westhoughton, might experience this more frequently due to general wear.

Could it be a different problem if my heating works?+

While a diverter valve is the most common cause, other issues like a faulty domestic hot-water flow sensor or a scaled plate heat exchanger can also lead to this symptom. Our diagnostics will confirm the precise fault.

Typical no hot water but heating works — safe first checks before you call work in Westhoughton

For Westhoughton householders and landlords dealing with safe first checks before you call. Local housing stock — 1990s–2000s developer estates alongside older terraces around Market Street — shapes how this work is carried out.

You have heating but no hot water.
Your boiler has no error code displayed.
You've checked your programmer settings.
You've tried a safe boiler reset.
You understand this is beyond basic user fixes.

What You Can Safely Check for Yourself

Your first steps should always be safe ones. We advise against opening up any boiler casing or touching electrical components. Most modern boilers have a display. If there's an error code, note it down. Sometimes, a simple reset can resolve temporary glitches. Also, verify that your heating programmer or smart thermostat isn't overriding your hot water demand. Ensure the hot water setting is clearly 'on' and not 'timed off' or 'winter mode' for heating only. These simple checks can sometimes save a call-out.

Perform a boiler reset if safe and accessible
Verify hot water setting on programmer/thermostat
Ensure no power cuts affecting the boiler

Understanding the Diverter Valve

The diverter valve is a key component in a combi boiler. When you call for hot water, this valve shifts, directing the hot water from the boiler's heat exchanger to your taps. If it gets stuck on the 'heating' side, your radiators will get hot, but no hot water will reach your taps. This is a common fault. The valve can become worn, or the motor that operates it can fail. This isn't something a homeowner can safely check or repair, but understanding its role explains why your heating still functions.
