glowworm-Ultimate-combi

The Glow-Worm Ultimate3 Combi is a user-friendly wall mounted combination boiler that does not require a cold water tank or hot water cylinder.

It measures 740mm (H) x 418mm (W) x 300mm (D) and is suitable for medium to large homes and properties where there is little or no loft space. This particular model features high hot water flow rates and is available in two different outputs of 30kW and 35kW.

As there is a choice of outputs on offer, Ultimate3 Combi prices vary from around £694.40 to £774.00. The boiler comes with a 5-year parts and labour warranty provided the boiler is fitted by a Gas Safe installer and the installation is registered on Glow-Worm’s Club Energy programme.

Boiler Energy Efficiency Credentials

With a seasonal efficiency rating of just under 90%, the Ultimate3 Combi is ErP A rated for heating and DHW (domestic hot water) efficiency. The unit has its own Grundfos modulating pump, which helps to reduce energy use and lower the cost of your fuel bills. This attractive boiler is also compatible with Glow-Worm’s full range of optional controls, meaning you can pay a little extra on some smart accessories to improve not only efficiency but also performance and comfort levels.

Ultimate3 Combi Technology and Main Advantages

Glow-Worm’s Ultimate3 Combi has an energy-saving Grundfos pump, as well as a high-quality automotive grade aluminium heat exchanger to provide exceptional performance. By being compact and lightweight, the boiler is quicker and easier to install so you could save money on installation fees. It also has an inbuilt filling loop for simple maintenance.

The range includes two output sizes with different maximum hot water flow rates, which are as follows:

  • Ultimate3 30kW Combi – 12.4 litres per minute
  • Ultimate3 35kW Combi – 14.4 litres per minute

Other key features include a modern interface with clear LCD display to enable you to have complete control over settings and temperatures. The boiler can even be used with Glow-Worm’s innovative MiGo app-based control which allows you to control your heating and hot water using a smartphone or tablet.

Is the Glow-Worm Ultimate3 Combi the Right Boiler Type and Size for Your Home?

Since the Ultimate3 Combi comes in two outputs with different flow rates, there is an option to suit a variety of property types and sizes. As a rough guide, the 30kW unit is suitable for a medium to large home with 1 bathroom, 1 ensuite and up to 15 radiators, and the 35kW model is ideal for a large dwelling with 2 bathrooms and around 20 radiators. Remember, the boiler heats water directly from the mains so you won’t need a cold water tank or hot water cylinder with this one. As we always say, it’s crucial for your new boiler to meet your needs, so you must contact a Gas Safe engineer to help you determine the right output for you home.

Our Honest Opinion of the Glow-Worm Ultimate3 Combi

Although not the most compact combi on the market, the Ultimate3 is A rated for energy efficiency and will save you a tonne of money on your energy bills if you’re looking to replace a much older boiler. And in case you’re unaware, Glow-Worm is a budget boiler brand, so you will be getting a decent boiler that isn’t going to cost the earth.

We should mention that Glow-Worm has upped its game in recent years, now designing and manufacturing products with top-quality components. Take the Ultimate3 Combi’s Grundfos modulating pump for example. This pump is one of the best in the business, with Grundfos being one of the world’s leading and best-known pump manufacturers.

Perhaps one of the most impressive things about this model is that you use it with Glow-Worm’s MiGo control to give you more control over the boiler, even when you’re not at home. However, this control isn’t supplied with the unit, but it can be purchased separately.

Advice on Boiler Quotes and Gas Safe Engineers

If you think the Glow-Worm Ultimate3 Combi is the right boiler for your home, we recommend you compare a range of quotes from different installers and boiler replacement companies to get the best price. It’s also important to make sure your chosen installer is Gas Safe registered and fully qualified to carry out the work that needs doing. You can check the credentials and registration status of an engineer by viewing the details on their ID card or checking the Gas Safe Register online. Don’t forget, you can save time and hassle by using our free service to receive no-obligation quotes from trusted suppliers and registered installers throughout the UK.
