We provide certificates with all of our boiler installations

After your new boiler installation is complete we’ll provide you with an Adey water quality certificate which could help to protect your boiler guarantee. Most manufacturers and quality installers will advise you to have a full central heating powerflush as part of any new boiler installation. The water quality ensures that your boiler installation can operate efficiently and will keep it in the best possible condition to minimize running costs and reduce the risk of costly breakdowns.

At Heatsy we’re trained and accredited by the two leading names in heating, Vaillant and Viessmann and can offer up to a 12 year guarantee on our installations.

A properly installed gas boiler will give you 15 to 20 years hassle free heating

New boiler installation with a full powerflush of the heating system

We strongly advise anyone with a new boiler installation to have a full powerflush of the heating system. A hot chemical flush or a magnacleanse will only remove surface dirt from the pipes and radiators, a boiler installation that hasn’t been flushed for 10+ years will have stubborn deposits of magnetite which will spread throughout the new boiler installation and could eventually void your guarantee.

New boiler installation with a gas safety certificate that protects your building insurance

Your new boiler installation also comes with a gas safety certificate to ensure your complete safety and peace of mind. A building regulations certificate is needed to prove you’ve had your boiler installation carried out by a competent professional, and ensure it’s legal to protect any building insurance you might have. It also gives you all the information about your guarantee and what you need to do to ensure it stays valid.

If you’re experiencing issues with your heating system we will be able to fix it, if not, we pay you double our diagnostics fee.

The Importance Of A Home Survey For Your Boiler System

The home survey is your opportunity to meet us before the boiler installation day. We don’t use salespeople, so the engineer you meet at the survey will always give you an honest assessment and answer any questions you might have.

During the home survey, we will talk with you to understand your routine and learn what’s important to you and what you want from your boiler installation. We will recommend different options bespoke to you and your family’s needs.

Once we have all the information we need we will present you with three packages, each designed to ensure that you have a boiler installation that works for you and gives you exactly what you want.

Please contact us to arrange an exceptional survey you can rely on.

    Heatsy completed our boiler repair quickly and efficiently.
    We called at 12pm and were offered two appointments, 4-6pm that evening or 8-10am the following morning at a lower rate.
    … More As it’s winter and mom was visiting from the US we decided to get the emergency appointment.
    The engineer called and text before he arrived and kept me updated throughout the work.
    Coming from the states we’re used to great customer service and I must say Heatsy made me feel right at home.
    Your slogan should be ‘British class with American service’
    I’ll be telling all the other moms at the next PTA meeting 😊
  • Avatar Zacharie Paimboeuf ★★★★★ 3 months ago
    Great boiler service, the engineer took everything apart and cleaned the inside and changed the seals.
    He also took a water sample from the boiler which showed the system was dirty
    … More and he was able to book me in to get my system cleaned without me needing to do anything.
    Very helpful and professional.
    Thank you
  • Avatar Sarah Luetchford ★★★★★ a month ago
    Was extremely helpful and explained what needed doing and was honest about what I needed to consider. Once he had finished and I messaged with an enquiry my engineer offered to come … More back and have a look. They sent a follow up message to ensure everything was still working and to check it was ok. Would definitely use again.
  • Avatar Martin Gilbert ★★★★ 3 months ago
    I had a combined boiler service with landlords gas safety certificate.
    The company were very professional and my tenant was very happy with the engineer.
    All paperwork and certificates
    … More were emailed in real time and I could track the engineer which is a nice touch.
    Four stars as the appointment had to be rescheduled due to over running work.
