With a central heating output of 25 kW and a hot water flow rate of 10.4 litres/min the Glow-worm Energy 25C combi boiler is a popular choice for use in smaller properties such as flats, apartments and houses with 1-2 bedrooms and 1 bathroom. As a new ErP compliant boiler, the 25C has been built to meet the new EU regulations concerning energy efficiency and, as an A-rated boiler model, you can rest assured you will be getting a high efficiency heating performance, something that can be seen in utility bills benefit in the long run. The Energy 25C model features a super-efficient aluminium heat exchanger that is designed to last a lot longer than your typical copper or alloy heat exchangers. The innovatively designed heat exchanger is extremely quiet and emits little sound during operation. The 25C boiler model is nice and compact too so can fit in most typical kitchen cupboard spaces, helping to free up room in the home by hiding the boiler away out of sight.

The Vaillant ecoTEC plus range of high efficiency boilers combine fantastic efficiency levels and high performance with great usability. Thanks to continuous modulation and real combustion control by a multi-sensor system, they achieve high efficiency at the lowest emissions. Due to the boiler's fantastic efficient performance, hot water heats up in just 5 seconds, meaning no hot water tanks are necessary. Perfect for larger homes, the ecoTEC Plus 938 combines the boiler and a storage tank, for a system that can pump around 20 litres of water per minute. Vaillant Combi Boilers are highly efficient and deliver a top SEDBUK Band 'A' rated fuel efficiency and powerful domestic hot water performance. Easy to install, a simple step by step wizard is included to provide a quicker 'first time right' set up, and removable side panels allow for greater access to the internal components, meaning the boiler will produce hot water as quickly as possible.

The Worcester 12i System Boiler is the perfect choice for small properties such as flats and bungalows. Offering compact dimensions, a low lift weight and A-Rated efficiency, the 12i has the potential to save money on annual heating bills and offer reliability through even the coldest months. The 12i System Boiler will require a hot water cylinder in order to deliver hot water to the property. The high efficiency of the 12i boiler can cut heating and hot water bills by 15-20% annually (When replacing an older, G-Rated boiler) and is up to 30% cheaper to run. These savings mean that over the years the boiler will essentially pay for itself, as the quality of Worcester boilers means that you won't need to replace it for many years. Easy to use, the Worcester 12i includes simple boiler controls to ensure your boiler is set at the correct temperature for the customer's need, while also providing operational information and diagnostics to help with maintenance.
