Product Description

The Ultimate3 Regular gas boiler is a compact, condensing and wall mounted unit designed and manufactured by Glow-worm.

As this is a condensing unit, it offers high efficiency, with an efficiency rating of 89.6% and ErP A rating. With an output rating of 25kW, the Ultimate3 is perfectly suited to larger homes with 2 or more bathrooms that have a higher demand for heating and hot water.

Thanks to its compact size, this boiler can fit into a kitchen cupboard and help to save valuable space around the home. As well as being small, the Ultimate3 is lightweight which will help to save money and time on the installation and future services. Despite its small stature there’s still room for plenty of features, such as a bright LCD display, easy to use interface, full compatibility with a range of accessories like the MiGo app so you can control the heating from your phone and a high-quality automotive grade aluminium heat exchanger

As this is a Regular boiler, also known as a Conventional or Heat Only boiler, it heats your central heating system directly and also produces hot water for your cylinder. Due to the fact that you need a hot water cylinder, often fed by a cold water storage cistern located in the attic, this type of boiler requires a lot of space so isn’t suitable for smaller properties or homes where space is limited.

Featuring a 5 year parts and labour warranty, you’ll be getting the peace of mind that your well covered long after installation.
