Welcome back to Compare Boiler Quotes’ boiler reviews. We have been researching and looking at boiler systems of all types and variants so that you can make the best choice on your new boiler.

If you have had a recent boiler breakdown, or have been told by a plumber or gas engineer that it’s time for a new boiler, then we can certainly empathise. Don’t worry though, as that’s what we’re here for. We have looked at hundreds of different boilers and their performance, pricing, warranty, and ease of installation/maintenance. We know their reliability, their energy savings, and other metrics which will help you to make the most informed decision.

We’ve looked at Glow-Worm in the past and their boiler systems are well recommended by us. 

In the course of our reviews, we try to look at a wide range of output systems so that each size UK home is represented.

In today’s review, we will be giving you the key features and pros and cons for one of the larger systems. If your home is 3 or 4 bedrooms and has multiple bathrooms then you want a system that has the output to supply the necessary hot water and heating. The Glow-Worm Ultimate 35c does this and more. But who are they and what is this new boiler like?

The Glow-Worm Ultimate3 35c Combi Boiler Output:

 

Glow-worm Ultimate 35c Review: The Family Home Boiler for the 21st Century. Compare Boiler QuotesThe Glow-Worm Ultimate3 35c is a high performance system for the modern family home.

The Ultimate3 35c is a highly efficient unit with an efficiency rating of 94% and ErP A rating to boot. The output of this boiler is an incredible 35kW! Making the switch from a regular or system boiler possible with the necessary output for your larger home.

Being a combi boiler system means that it heats the hot water on demand and doesn’t require the extra space, installation, and maintenance that comes with having a system with external cylinders or loft tanks.

This also makes this unit perfectly suitable for larger homes with many bedrooms and 2 or more bathrooms.

For example, this system has the necessary output to supply a 4 bedroom, 2 bathroom family home with up to 20 radiators. It also means that you can use 2 bathrooms simultaneously should you have kids who require the use of multiple bathrooms.

 

Sizing and Key Features:

 

The Glow-Worm Ultimate3 35c is a compact unit capable of being wall mounted. This model, despite its high output, can be installed away in a cupboard and will not be noticeable at all due to low sound output even in full operation.

Even though this is a compact boiler, there’s still plenty of room for some thoughtful high end touches and features, such as a bright LCD display and easy to navigate visual system , giving you a simple control of the whole system and it’s electronic settings.

It also has a high-quality and high grade aluminium heat exchanger for even more reliable performance as well as a Grundfos modulating pump.

This is key in helping to reduce your energy bills.There’s also a wonderfully designed filling loop for simple and really straightforward maintenance. 

With a wide range of flue options, the flexibility gives it an even easier installation in multiple locations in your home.

Warranty:

The warranty is always our key sticking point and many companies will force you to have their system installed by a registered or accredited fitter. This boiler system is a little different however, as they offer you a fantastic 10 year warranty but you simply have to register the system to activate it. This means Glow-Worm must have the confidence in their system to offer such a warranty. 

 

Conclusion and Alternatives:

 

Glow-worm Ultimate 35c Review: The Family Home Boiler for the 21st Century. Compare Boiler QuotesWe think this boiler is a great choice for family homes due to its output, performance, and efficiency. It is truly a highly capable modern combi boiler and with the addition of a 10 year warranty can it be beaten? 

Well, considering the fact that the flow rate is 14.4L and it has an aluminium heat exchanger, we think that the Viessmann Vitodens 111-W is a much better choice.

With the 35kw having the internal storage capacity of a 150L cylinder system, and a high end stainless steel heat exchanger , it is of much more robust and efficient construction.

It also has a flow rate of 18L so it will fill your bath much more quickly than the Glow-Worm system. The pricing is also similar so this is why we recommend this system. It is also available with a standard 10 year warranty which can be 15 years by choosing Boiler Central as your installer.
