About

I'm Allen Hart, and I run a plumbing and heating company in Leeds. I created this website and my videos to share practical advice, industry insight and hands-on demonstrations with heating engineers, plumbers, trainees, capable DIYers and homeowners.

The site covers boilers, central heating, plumbing, gas safety, fault finding, electrical safety, controls and home energy. The aim is to explain how systems work, help readers find reliable answers and make it clear when a task should be left to a suitably qualified professional.

Start with the most-read Allen Hart guides

These are two of the most visited articles on the site:

• Regulation 26.9 gas engineer safety checks – a detailed explanation of the flue, combustion-air, operating-pressure or heat-input and safe-operation checks required after work on a gas appliance.
• Strom E-Boiler E5 error code explained – what the inadequate-flow warning means, common causes, safe checks and how the boiler is reset after the fault has been corrected.

Practical heating and plumbing advice

Many of the guides begin with a real fault, maintenance question or installation issue. Some are written for professionals, while others explain straightforward checks that a homeowner may be able to complete safely.

Popular heating and plumbing guides include:

• How to bleed a radiator that is not getting warm
• How lowering boiler flow temperature may improve efficiency
• How to clean a central-heating magnetic filter

Every installation is different. Boiler settings, system pressure, controls and maintenance procedures should always be checked against the instructions for the equipment fitted in the property.

Gas engineer training and safe working

The professional content is intended to support training and continued learning rather than replace manufacturer instructions, current regulations or recognised industry procedures.

Engineers and trainees can explore the plumbing and heating training section or read the guide to electrical safe isolation when working on boilers.

Gas safety: Gas work must be carried out by a Gas Safe registered engineer who is qualified for the particular type of appliance. Homeowners can check an engineer’s registration and work categories through the official Gas Safe Register.

Videos and hands-on demonstrations

Some jobs are easier to understand when you can see the components, tools and testing sequence. The Allen Hart video library brings together demonstrations covering boiler faults, plumbing techniques, heating controls and engineer training.

The written guides provide additional explanations, safety notes and links to related topics. Browse the complete Allen Hart heating and plumbing blog to see the newest articles.

Home energy and changing heating technology

The site also follows developments beyond conventional gas heating, including heat pumps, solar energy, battery storage and electric-vehicle charging.

For an introduction to domestic charging equipment, electrical requirements and installation considerations, read the UK home EV charger guide. New energy and renewable-heating articles are added to the main blog as the technology and available guidance develop.

Who is the website for?

• Heating engineers and plumbers looking for practical technical content and industry discussions.
• Trainees and newly qualified engineers building their understanding of systems, controls, testing and safe working.
• Capable DIYers completing appropriate plumbing or heating-maintenance tasks within their competence.
• Homeowners and landlords trying to understand their heating equipment, common faults and professional safety checks.

Technical articles clearly distinguish between sensible user checks and work involving gas, internal electrical components or specialist testing.
