Repairs for Every Kind of Hatfield Home

The boiler fault we find often depends on when the house was built. In Roe Green, Oxlease and South Hatfield, many homes have a boiler feeding a cylinder through motorised zone valves, and when one of those valves sticks you get heating with no hot water, or the other way round. In Salisbury Village, the combis and system boilers fitted when the homes were new are now old enough for diverter valves, fans and circuit boards to start failing.

We also look after a lot of rented properties, including student houses near the University of Hertfordshire. For landlords that means quick diagnosis, a clear report of what was wrong and a repair that keeps the tenants warm and the property compliant.

We diagnose the fault first, tell you the cost, and only then carry out the repair. If the boiler is past saving, we will be straight with you about a replacement boiler. For other work in the town, see our Hatfield plumbing and heating page.

Typical Faults by Type of System

Knowing the system helps us bring the right parts first time.

  • Heating But No Hot Water: On tank-fed systems this is often a stuck motorised valve or a failed cylinder thermostat.

  • Hot Water But No Heating: Usually a zone valve, a room thermostat or a pump that has stopped circulating.

  • Combi Hot Water Faults: In older Salisbury Village combis, a worn diverter valve or a scaled heat exchanger causes hot water that comes and goes.

  • Unvented Cylinder Issues: A dripping relief valve or a failed expansion vessel on an unvented cylinder needs prompt attention.

  • Lockouts: Ignition and flame detection faults that cause the boiler to lock out repeatedly.

Call Us If You Notice

These signs usually mean a fault is developing.

Heating and Hot Water Out of Step

One works and the other does not, often a valve or thermostat problem.

Repeated Resets

A boiler that needs resetting regularly has a fault that will get worse.

Tenant Complaints

For landlords, repeated reports of cold showers or radiators should be checked before they escalate.

Pressure Gauge Falling

Pressure that drops means water is escaping from the system.

Really happy with the work carried out by Alban Plumbing and Heating. They fitted several new radiators in my home and the whole process was smooth from start to finish. They arrived on time, were friendly and professional, and took great care while working in the house. The installation was completed to a high standard, everything was left clean and tidy, and the new radiators look fantastic and heat up perfectly. It's refreshing to find a company that is reliable, communicates well, and clearly takes pride in their work. I wouldn't hesitate to use Alban Plumbing and Heating again and would happily recommend them to friends and family.

Asif has done a great job looking after our plumbing and heating for several years now. He also recently attended in under an hour to fix an emergency leak that he and his son sorted with great efficiency allowing us to get back to work and continue operating with minimal disruption to our business and patients. He’s reasonably priced and friendly and I’m sure we will be using him for many years to come. His 5 star status is well deserved.
