Advanced Heating Technology & Your New Boiler Installation in Chelmsford

Many of the heating systems and solutions on the market today allow you to set and manage the heating in your house using an app on your mobile phone. This makes it possible to regulate your heating remotely when you are away from home. Imagine having the ability to switch on your heating with only a swipe of your finger as you board the train for your daily trip home during the chilly winter months. That way, when you come through your front door in 30 minutes, your house will have the cozy, warm atmosphere we all long for. Do ask us about all the smart technology that is available to you now as we can advise you on what we have found the best systems to be and how you can interact with them and your heating.

Power Flushing & Your New Boiler in Chelmsford

If you are having a new boiler installed in Chelmsford we would also recommend that you have your central heating system power flushed.  Power Flushing is a process that shoots water at high speed around your central heating system and it effectively flushes out an build-up of deposits within the radiators that can often cause dead spots on the radiators or get flushed around the system back into the boiler, causing more problems with your heating. It is a system that essentially cleans your central heating system inside. Do ask us about this as if you have not had this carried out in the last 5 years it may be worth undertaking if you are having a new boiler fitted.

Boiler Installation FAQs in Chelmsford

Got a question about getting a new boiler fitted in Chelmsford? Here are the answers to the questions our engineers are asked most often. If yours isn't covered, give us a call and we'll be happy to help.

How long does it take to install a new boiler?

A like-for-like combi swap is usually completed in one day. Converting from a system or regular boiler to a combi, or moving the boiler to a new location, typically takes two to three days.

Will I be without heating and hot water?

Only on the day of installation. We'll agree a time with you in advance and keep disruption to a minimum.

Do you remove my old boiler?

Yes. We remove and responsibly dispose of your old boiler and any redundant tanks or cylinders.

Should I repair or replace my boiler?

If your boiler is under 10 years old and the fault is minor, a repair is usually the better value, and we'll always tell you honestly. If it's older, inefficient or needs expensive parts, a replacement often pays for itself through lower bills and fewer callouts.

Is the survey really free?

Yes. There's no charge and no obligation to go ahead.

How often does my new boiler need servicing?

Once a year. Annual servicing keeps your boiler running efficiently and is required to keep your manufacturer warranty valid.
