Boiler Installation

I understand that installing or replacing a boiler in a home is a major item of work involving expense and disruption. I look to minimise any disruption by, in most cases, completing a boiler replacement within two days. I aim to make you boiler installation as painless as possible.

I spend every day of my working life working in people’s homes, so I understand the importance of being clean and tidy whilst I work. I am also respectful of the property owner’s space. We are a family business and drive much of our business from repeat custom and customer referrals, this is a practice which is core to our business.

Makes of Boiler I recommend and Install

I install most manufacturers of boiler. I do, however, have preferred boiler manufacturers whose boilers I know offer an economical solution over their life time; in other words, I have found the cheaper boilers to be a false economy as their lifespan is generally lower and annual servicing costs higher.

Boiler manufacturers I recommend and whom I regularly supply boilers:-

  • Valliant
  • Worcester Bosch
  • Glow Worm
  • Baxi

I am qualified and trained to work on the majority of boiler types available today, I do however find that the following types of boiler for the majority of new installations or replacements:

  • Gas fired condensing boilers
  • Combination boilers
  • System boilers

If, however, you would like a quote for the replacement or installation of another boiler type I am qualified to undertake the majority of domestic boiler installation work and I am happy to provide you with a quotation for this.


All workmanship is undertaken and covered by a 12 month workmanship guarantee; all supplied materials and products are covered by manufacturers guarantees and the majority of the boilers I supply come with a 5 year manufactures guarantee.


Boiler Service

Boilers should be serviced each and every year to ensure continued and safe operation. Our professional fitters doing your boiler service are Gas Safe Registered (this accreditation has replaced the commonly-known CORGI certificate), expert heating engineers.

To include:

Visual check

the boiler service starts with a visual check that establishes that the boiler, its installation and its positioning, comply with the rules laid out in building regulations, electrical regulations, gas-safety regulations, water by-laws, installation instructions and British Standards. All must comply with present legislation.

Pre-service Check

to do this the boiler engineer will fire the boiler, check its basic operation and identify any initial faults. A gas rate check is also done.


The casing will be removed (something you, as the householder, should never do yourself). At this point the main components will be examined to see they are clean and free from damage. These components include the main burner, the main injector, and the heat exchanger, condense trap, the spark centre probe and the seals and fans. Also part of this section of the boiler service is the checking of all electrics for overheating, the cleaning of all inside surfaces, inspecting all pipe work (water & gas) and joints, and very importantly, making sure the flue terminal is unobstructed.

Flue Gases Check

Flue gases are checked with a flue gas analyser to make sure the boiler is combusting properly. The results are recorded.

Test Results

If any of these tests show a fault, the engineer should inform you of any additional costs that the repairs will incur. It is widely recommended that the parts are only replaced with those also made by the manufacturer of the boiler, to ensure that they’re compatible.


The boiler engineer will carry out a gas-tightness test to establish if there are any leaks in the system.

Boiler Service Report

The casing of the boiler should then be carefully replaced and your report is produced. This is your chance to compare what the boiler engineer has stated they have done, with what has actually been completed. Only sign-off the report if you are satisfied with the work done compared to the checklist.


Gas Safety Certificates

With all the gas appliances and pathways in the standard home, its little wonder that gas safety testing has been written into law. Safety is always a major issue where gas appliances and fixtures are concerned, so having gas safety testing and certification by a Gas Safe Registered Engineer is a critical step.


If you own a property in which you have tenants, you are required by law to have the gas supply, boiler, appliances and flues checked and certificated annually.

As a Gas Safe engineer, I’m authorised to carry out this check for you, and to issue the CP12 certificate that you must supply to your tenants within 28 days of the inspection, or at the time that they move into the premises.

When I carry out the check, I leave a copy of the certificate with/for your tenants, as well as providing a copy to you.

I can set up an annual reminder for you, so that you don’t have to give any further thought to this. Each year I will then contact you when the check is due, and make arrangements to go in and do it.

I can liaise with your tenants and/or managing agents over collecting and returning keys, and I can email electronic copies of the CP12 directly to you.


It is your legal obligation to get a new gas safety certificate every twelve months, according to the Gas Safety Regulations (Installation and Use) from 1998. The certificate is known as a CP12, and it is required for any pipe work, flues and gas appliances that are installed on your property.

At Daniel Sheen Plumbing & Heating I can carry out gas safety checks for you and issue you a Homeowner’s Gas Safety Certificate (CP12) detailing the checks carried out, for your peace of mind.


If you live in a rented property you should have been supplied with a current valid copy of the CP12 Gas Safety Record Certificate at the time that you moved in. This must be renewed every year by your landlord, and a copy of the new certificate provided to you.

If you do not have a current CP12 certificate, contact the managing agent who looks after the property or your landlord directly, and ask them for one. If you pass on our details to them, I’d be pleased to come and carry out the check, issue the certificate and send a copy to the landlord by email

What Does the CP12 Include?

The CP12 shows the following:

  • A description and the location of each appliance and/or flue that I’ve checked
  • The name, registration number and signature of the engineer who carried out the check
  • The date on which the appliance and/or flue was checked
  • The address of the property at which the appliances and/or flues are installed
  • Any defects identified and any action required or taken to fix these
  • Confirmation of the results of operational safety checks carried out on the appliances

Vented & Unvented Water Systems

I offer servicing and repairs of existing systems, unvented cylinders are required to be serviced every 12 months

Hot water cylinders are a crucial element when it comes to delivering hot water to your home. They are designed to keep the water hot as it is being stored, so it is ready when you need it. There are two main types of hot water cylinder to choose from; vented and unvented. Each type has its own characteristics and benefits.

Difference between Vented and Unvented

Vented and unvented hot water cylinders have different set ups. A vented cylinder uses a vent pipe that makes it react to the current atmospheric pressure. The mains water is fed to a cold water storage tank, and it is stored there until needed by one of the appliances in your home. Unvented cylinders work directly from the mains water, and while the principle is the same, the flow of water can be better.

Benefits of a Vented Cylinder

The benefits of using a vented hot water cylinder in your home include being less complex to install and less costly to install and maintain. This indirect heating method is more economical overall, which is the only real option for many homeowners who are on a strict budget.

I install, maintain and replace traditional vented cylinders, fed from cold water storage tanks that are normally located in your loft space. I are able to carry out all work on these cylinders, and can supply new cylinders at good prices using our trade discount.

Benefits of an Unvented Cylinder

With an unvented cylinder, hot water is provided at mains pressure, so the flow is better and more dependable. Typically, showers are more enjoyable and you can use less space because there is no need for a cold water storage tank. The fact that mains pressure is being used and not just gravity, you can position the cylinder almost anywhere and it will still work effectively. These unvented cylinders are more costly than their vented cousins, but the greater water pressure is worth it for many people.

Whichever system you decide on, make sure you bring in a reputable, experienced and fully-qualified engineer to install the cylinder for you. Corrections and repairs after a poor quality installation can be costly, and badly installed unvented cylinders can potentially prove more dangerous than a gas explosion, so leave the hard work to professionals.

Installing a New Hot Water Cylinder

I install, maintain and repair all types of hot water systems, from electric to gas heated. As every property is different, and everyone has their own requirements, it’s best to talk to us if you’re refurbishing your property or you want to replace your existing hot water system to make it more efficient (or to free up space that’s being occupied by a large cold water tank or an unnecessarily bulky old cylinder).

One of our technical experts will come over to discuss your requirements with you. He’ll check over your property’s specifications and then suggest the best solution for your particular needs.

Whatever your requirements, a cylinder from the Megaflow range will very often provide the solution you are looking for. There are a wide range of models to choose from, for use with and without external boilers, and in a range of sizes suitable for even very large properties.
