Nicholsons Heating - Five Star Service

We had our regular boiler replaced with a combi boiler by Nicholson’s Heating in February 2023. Now, two years later, we feel it’s the perfect time to share a considered review of the system and its long-term performance. In short, we couldn’t be happier with the results.

Switching from a regular boiler to a combi boiler was a decision we made carefully. Our main goals were to remove the cold water tanks from the loft, reducing the risk of leaks and freezing, and to free up space in the house by removing the hot water tank from the airing cupboard. These changes have allowed us to make much better use of our home, and the results have exceeded our expectations.

We chose an ATAG IC Economiser 35 Plus combi boiler, which was quite an expensive option, but it has been worth every penny. This boiler is extremely economical—identified as the most economical boiler in Europe—and it has lived up to its reputation. Our central heating system now works superbly, and we enjoy a constant supply of hot water thanks to the switch to a combi boiler. The boiler has been incredibly quiet in operation and far less costly than the alternative of a heat pump, both in terms of running and installation. It is easy to forget that the electricity to actually run a heat pup is three times more expensive than gas per kWh, quite apart from the installation costs.

The overall installation has proven to be 100% reliable. In nearly two years, we have had no problems whatsoever. The team from Nicholson’s Heating who carried out the work were absolutely excellent—superior in every way. They completed the job on time, within the agreed budget, and within the specified time period. Their professionalism, attention to detail, and good humour made the entire process stress-free.

We were also impressed by the long-term warranty provided with the boiler. We decided to pay a little extra to extend this to 14 years, covering all parts and labour, with a lifetime replacement guarantee on the heat exchanger. This has given us tremendous peace of mind, knowing that we’re covered for years to come. Annual servicing, carried out by Nicholson’s Heating, has also been extremely cost-effective, ensuring the warranty remains valid.

As part of the installation, we opted for the Hive wireless control system instead of Nest, and it has been absolutely brilliant. It allows us to control the boiler via the Internet when we’re away from home, and the usual timer and thermostatic controls in the wireless package work seamlessly. The Hive system has been flawless, with no glitches whatsoever, and we highly recommend it to anyone considering a similar setup.

In conclusion, we cannot recommend Nicholson’s Heating, the ATAG IC Economiser 35 Plus boiler, and the Hive system highly enough. This has been a terrific installation that has transformed our home’s heating and hot water system. It is economical, reliable, and efficient, and the workmanship was second to none. A huge thank you to Nicholson’s Heating for a job done to the highest possible standard!

We have no hesitation whatsoever in recommending Nicholson’s for your heating needs.
