At iWarm, we are proud to be your local, Gas Safe Registered (Registration Number: 932713) heating experts based right here in Grimsby, North East Lincolnshire. Our comprehensive central heating services are designed to keep your home warm, safe, and incredibly energy-efficient all year round.
Complete Heating Solutions
As a heart of your home’s comfort, your heating system consists of multiple vital components. We offer a full suite of services to ensure every part of your system works in perfect harmony.
Boiler Installations
If your old boiler is constantly breaking down or costing a fortune in energy bills, it might be time for an upgrade. We provide professional, energy-efficient boiler installations tailored to the specific heating demands of your property. We work with the industry’s leading manufacturers to ensure your new system is built to last.
Boiler Repairs
A broken boiler can bring your household to a standstill. Our expert diagnostic team is on hand to provide rapid, reliable boiler repairs. From faulty pumps to pressure issues, we carry the parts and the expertise to get your heating system back up and running safely and efficiently.
Radiators
Are your rooms taking too long to heat up, or are you looking to modernise your home’s aesthetics? We supply and install a wide range of high-performance radiators. Whether you need a simple valve replacement, a leaky radiator fixed, or a complete property refit with sleek designer units, we ensures optimal heat distribution in every room.
Central Heating Pipework
The hidden veins of your central heating system are just as important as the boiler itself. We handle all aspects of central heating pipework, from repairing hidden leaks to rerouting pipes during home renovations. If your system suffers from poor pressure or flow, upgrading your pipework can often instantly restore its performance.
Central Heating Flushing
Over time, sludge, rust, and debris can build up inside your central heating system, drastically reducing efficiency and potentially causing terminal damage to your boiler. We specialise in comprehensive system cleaning, offering both Chemical System Flushing and advanced Magnacleanse System Flushing to clear blockages, protect your pipework, and restore your system’s efficiency.

Frequently Asked Questions
How do I know if my central heating system needs flushing?
If your radiators have cold spots (especially at the bottom), your boiler is making loud "kettling" noises, or your system takes a very long time to heat up, a build-up of iron oxide sludge is likely the culprit. A professional Magnacleanse or Chemical Flush can resolve this.
Should I repair my old boiler or replace the whole central heating system?
If your boiler is over 10-15 years old, constantly requires repairs, or has a poor energy efficiency rating, replacing it is often more cost-effective in the long run. Our engineers can assess your current central heating setup and offer honest advice on the best route forward.
Do you cover emergency central heating repairs in Louth and Lincoln?
Yes, while we are based in Grimsby, our engineers frequently travel to Louth, Lincoln, Scunthorpe, and the surrounding towns to provide urgent boiler and heating repairs.
How often should my central heating system be serviced?
To maintain optimal efficiency, ensure safety, and keep your manufacturer’s warranty valid, your gas boiler should be serviced by a Gas Safe registered engineer once a year.
How much does it cost getting my central heating repaired?
Our central heating repair service starts at £80 depending on your requirements. Most heating jobs can be quite complex to price, so please contact us for more information.

I had a boiler issue, stopped working. He arrived on the same day and ensured that the boiler works while we wait for parts. Kept me updated while parts were coming and asked if the boiler is still working. Always kept the area clean and explained what was the issue. Great job! Definitely recommend.Posted on Google![]()

Fantastic service from Guy, who travelled out to Market Rasen on a Sunday when our boiler stopped working. He was super professional, quick to sort the issue, and great value for money. With kids in the house, getting the heating and hot water back on meant everything, definitely one of those luxuries you take for granted until they’re gone. Really appreciate the effort and would highly recommend.Posted on Google![]()

Guy came to us today which was a wet and cold Sunday afternoon as my Elderly Mother was without heating. After initial contact a time was agreed and Guy arrived on the dot.... He was very good and explained everything he was doing ensuring we understood what was happening. Guy was very clean and there was not a single bit of mess left behind. He made sure we were happy with the work and didnt leave until he was 100% sure the problem was fixed. There was no hard sell with Guy at all he explained a few options for us in the future. Would HIGHLY reccommend Guy and have saved his details for future use. 5☆☆☆☆☆Posted on Google![]()
