High-efficiency boilers built to last

ATAG iC Economiser Plus Combi Boiler

Combi boiler of the future

The revolutionary iC Economiser Plus  boiler has been described as the COMBI OF THE FUTURE because it contains an industry-leading innovation, the patented Economiser Plus.

Inside each ATAG Economiser Plus combination boiler, there is a revolutionary device that recycles lost heat. In doing so, it protects

 the environment while helping to save money on your annual gas bills. 

Some years ago, Atag design engineers realised untapped residual heat left in the boiler after hot water had been heated. Rather than release this energy as waste, they engineered the Economiser Plus, an environmentally-friendly innovation that recycles the flue gases for a second time, resulting in optimum energy efficiency.

"We now look forward to reduced operational cost through the two new ATAG boilers with a 10-year warranty, improved zoning and control systems. Matt's work was again to a very high standard, and we highly recommend him to you. 5 stars."

This customer initially contacted us in Chigwell to carry out an annual boiler service. The service was completed, and a conversation with the customer regarding the efficiency and availability of spare parts highlighted a potential future problem that the customer hadn’t thought about as peace of mind was not an option with their current 30-year-old installation.

The following day we emailed a fixed price quotation to the customer, which included removal of the storage tanks, radiators and existing boiler.

It was agreed that an ATAG combination boiler would be installed with new efficient radiators and a more accurate wireless programmable room thermostat.

The installation took three days and left two delighted customers with a very efficient system that gave them peace of mind with 10-year parts and labour warranty and a much more comfortable heating system.
