Ideal Logic Max System 30 Review

Ideal is a boiler brand steeped in British heritage, having been founded all the way back in 1906. As a company, it’s known for its reliable boiler systems and competitive price points. 

One of Ideal’s best selling boilers is the Logic Max System 30. This award-winning system boiler offers all the essentials that you would expect from your boiler, all whilst at an affordable price, too. So, if you need a new combi boiler – and you’re on a budget – then check out this Ideal Logic Max System 30 review to see if it could work for you and your home.

Why Choose the Ideal Logic Max System 30?

With an A ERP rating, this boiler system is a great eco-conscious choice that could even help you reduce your energy bills with its efficiency sitting at a highly-impressive 93%. When it comes to how many radiators the Ideal Logic 30 system can heat, it’s definitely better-suited to larger properties, with between 15-20 radiators. Check out our round-up of the key features you need to know about:

The Ideal Logic 30kW system boiler is compact for a kitchen cupboard fit, meaning that it’s discrete to install, but you will also need a hot water cylinder, however. As well as being scratch-resistant and hard-wearing, it comes with a large, user-friendly, digital backlit display so there’s no squinting to see how your settings are configured! Here are some other factors to consider:


  • Boiler Frost Protection
  • Built-in service indicator that provides service reminders
  • Good for larger homes with high hot water demands
  • Easy to install
  • Good quality Ideal system filter that improves efficiency to help maintain low running costs
  • Compatible with Ideal controls


  • Not suitable for homes without a hot water cylinder
  • Requires space for a cylinder
  • Pre-programming required for hot water at specific times
  • Not compatible with solar panels

The pros really do outweigh the cons with this boiler, and it’s hard to fault it. When you take into consideration the price and energy rating, it’s an incredibly strong choice for those looking for both affordability and reliability.

The One Significant Downside

Space Demands

This system boiler will take up more space than a combi boiler as they produce hot water that needs to be stored in a separate cylinder.

The boiler itself is very compact and will neatly fit inside a kitchen cupboard but typically, you would want your system boiler and cylinder together, so this space demand is something that needs to be considered.

That being said, if this is a direct swap then the space requirements shouldn’t be an issue as there will already be existing space for a cylinder.

Are Ideal Logic Boilers Reliable?

A company that has well and truly stood the test of time, Ideal is a Which? trusted brand that has built a reputation for reliable boilers that won’t break the bank. 

As a company, Ideal is rated as excellent (4.8) on Trustpilot, which continues to reinforce its status as a market leader. If you need any further reassurance, however, then look no further than the 10-year warranty on offer, which provides owners with security in the unlikely event that the boiler fails.

Ideal Logic’s main competitor is Worcester Bosch, who are the UK’s top boiler manufacturer, but they only offer aluminium heat exchangers whereas Ideal offer stainless steel. Aluminium heat exchangers are effective and efficient, but don’t offer the same level of protection against rust that stainless steel will. This means they are more likely to require replacing before a steel counterpart would. 

For a more premium boiler, Worcester is the way to go, but for a budget-friendly alternative, Ideal is highly reliable and energy-efficient, as well as coming with the added benefit of a stainless-steel exchanger. There are several other alternatives to the Ideal Logic Max S30 from Alpha and Vaillant. We’ve grouped together their key specs here:

Brand Ideal Logic Max S30 Alpha E-Tec 30S Vaillant ecoTEC Plus 630
Price £1227 £945 £2676
Output 30kW 29.7kW 30Kw
ERP rating A A A
Energy Efficiency Rating 94% 93% 89.40%
Size (H x W x D) 700 x 395 x 278 mm 712 x 440 x 256 mm 720 x 440 x 372 mm
Weight 26.1kg 33.2kg 40kg
Warranty 10 years 7 years 5 years
Wall Mounted Yes Yes Yes

The Ideal Logic 30kw system boiler is the mid-range price point option of the three but has a better energy efficiency rating when compared to the other two. It’s also more compact and less weighty than its counterparts and offers a longer warranty to boot. Although you may save money on the cost of the boiler with the Alpha E-Tec 30S, it is likely to cost you more in energy costs in the longer-term, when compared to the Ideal Logic model.
