No Hot Water, Heating Works: Your Pemberton Fault Visit Explained

When your radiators are toasty but your taps run cold, it's a common and frustrating problem. What we usually find on site is that the boiler itself isn't completely kaput. The heat is there, it's just not getting where it needs to go for your hot water. This often points to a specific component that directs the heat, commonly known as the diverter valve, getting stuck on the heating side. During our visit, we methodically test the system to pinpoint the exact cause, ensuring an efficient and effective repair for your home in Pemberton.

What We Test For On-Site

My primary goal is to diagnose the fault accurately and efficiently. First, I'll check if the boiler is actually receiving the 'demand' signal for hot water. If the boiler thinks you haven't asked for hot water, it won't provide it. Then, I'll verify the diverter valve's actuator motor is moving correctly, as this is responsible for physically directing the flow. Following this, I'll assess the flow through the plate heat exchanger, which transfers heat to your domestic hot water. This diagnostic order saves time and prevents unnecessary part replacements.

Practicalities During The Visit

Before any work, I'll ensure safe isolation of the boiler's power and gas supply. Access to the boiler's internal components will be required, so please ensure the area around it is clear. Depending on the diagnosis, parts may need replacing, such as the diverter valve cartridge or the actuator motor. I carry common spares, but specific or older models might require ordering. Any replacement work will be done to Gas Safe standards, followed by testing the system thoroughly to confirm the hot water is restored and working safely.

After the repair, your hot water will be working reliably again. I will always explain the work carried out, show you the replaced faulty part if applicable, and ensure you understand any maintenance advice. You will receive a full electronic service report detailing the diagnostic steps, the fault found, and the parts used. This report is your record of the work done and ensures transparency. My aim is to leave you with peace of mind and a fully functional hot water system.

Pemberton FAQs — no hot water but heating works — what happens on the visit

Will you need to drain my whole heating system?+

Generally, no. For most 'no hot water but heating works' faults, only a small amount of water from the boiler or specific components might need draining, not the entire heating system. This speeds up the repair process significantly.

What if the fault is not what you initially suspect?+

My diagnostic process is designed to systematically rule out causes. If the initial checks don't pinpoint the issue, I will proceed to the next diagnostic step, such as checking NTC sensors, until the exact fault is identified. The approach is methodical.

How long does this type of repair usually take?+

Diagnosis can often be completed within the first hour. If parts are readily available and straightforward to fit, the repair could be completed on the same visit. More complex issues or specific parts might extend the timescale, but I'll keep you informed.

Is this problem dangerous for my boiler?+

While inconvenient, a 'no hot water but heating works' fault isn't typically dangerous. It means a component isn't performing its function, but the boiler's safety mechanisms should still operate correctly. We ensure all repairs meet safety standards.

In summary

This page details the Gas Safe engineer's on-site process for diagnosing and fixing 'no hot water but heating works' faults. Expect methodical testing, clear explanations, and a full service report.
