Ideal Logic Combi 30 Plus: Boiler Review (2023)

Ideal Boilers is a thriving UK boiler manufacturer that now produce 6,000 boilers per week. And the Ideal Logic Plus 30kW combi boiler is one of the most popular in the Ideal Logic range. Today, we’ll review the Ideal Logic Plus in detail, comparing it directly to the equivalent Worcester boiler.

Ideal Logic Combi Plus 30: Boiler Overview

Firstly, don’t confuse the Logic Plus (or Logic+ Combi) range of boilers we are about to review with the standard Logic range of boilers. The latter are known as the Ideal Instinct range in some plumbing merchants.

The standard Logic boiler only comes with a 2-year parts and labour warranty — which is alarmingly short. You definitely want to fork out the extra for the Plus model boiler and grab that extra warranty coverage.

The Logic Plus range boasts a no-hassle 7-year warranty period. Better still, it’s A-rated, ErP compliant, and offers over 91% efficiency (which means it’s on par with the equivalent Worcester Bosch boilers).

Ideal Logic Combi Plus 30 vs Worcester Bosch Greenstar 4000

Whether you’re reading an Ideal, Vaillant, Baxi or even Vokera review, you’ll likely draw comparisons with a Worcester Bosch. That’s the power of branding!

For the Ideal Logic Combi 30, the equivalent Worcester Bosch product used to be  the Worcester Bosch Greenstar 30i. Nowadays, it’s the Worcester Greenstar 4000 30kW.

Ideal vs Worcester Boiler Costs

If you’re weighing your options for boiler replacement installations, here are the approximate prices for the Logic 30kW plus and the Worcester Greenstar 4000 equivalent:

• Ideal Logic Plus 30kW: £1,995 including installation
• Worcester Greenstar 4000 30kW: £2,040 including installation

You can compare prices for the Ideal Logic Plus Combi 30 and the Worcester 4000 boilers from Heatable in less than 90 seconds.

Other Cost Considerations For a New Boiler

To get Worcester’s full boiler warranty, you’ll need to purchase their branded controls and system filter. We documented that in our review of the best combi boilers. But the flues and flue accessories are also slightly more expensive than Ideal Boilers’.

In terms of extra boiler fitting costs, branded controls, filter, flue, accessories, and extra labour, comes to a difference of approximately £300 extra for a Worcester boiler over its Ideal counterpart.

However, Worcester Bosch have excellent deals with an online boiler installation company, Heatable. So naturally, Heatable are one of the most competitive companies when it comes to installing Worcester boilers. In fact, using a local installer for a new Ideal Logic Plus will be comparable in price to getting a Worcester 4000 using Heatable.

Ideal Logic Plus 30 Combi — Boiler Additional features

• Backlit digital display with easy-to-see pressure gauge.
• Never miss a boiler service with their newly built-in service indicator.
• Reduced mechanical parts for extra reliability (using top-brand components such as Honeywell)
• Compatible with a huge range of additional controls.
• Comes with an integral filling loop and built-in automatic bypass valve.
• Boiler frost protection technology built in that reduces the probability of a breakdown.
• Fully modulating operation to low outputs, which can help you save on energy bills.

Suitable Property Size

The Ideal Logic Plus 30kW combi boiler is suitable for mid-range properties. So, we are roughly talking about 3-4 bedrooms with a single bathroom (2 max) and reasonable demand for hot water (i.e. not 2 showers and a tap running at once).

Smaller properties are better suited to the Ideal Logic Plus 24kW boiler, whilst larger properties would need the Ideal Logic Plus 35kW.

Combination boilers heat hot water on demand, so output is extremely important (speak to your engineer if you are unsure which size is suitable for your property).

If your property has more than 2 bathrooms, or excessive demand for hot water, it’s likely you’ll need either the Logic Plus 35kW combi, or even a system boiler.

Suitable Installation Area [Awesome Compact Design]

Most other boiler brands produce a compact range (Worcester has the CDI Compact, for instance) which are designed for the sole purpose of fitting into a kitchen cupboard. The Logic Plus 30 boilers will fit into a kitchen cupboard as standard — making them the perfect choice for properties with limited space. 

Here’s the spec sheet from Ideal Boilers Logic Plus:

Ideal Logic Combi Boiler Warranty

You’ll be getting a 7-year standard product warranty with any Logic Plus boiler. We’d always suggest heading for a boiler that gets a 5-year warranty or higher, so there’s no problem there.

However, you can get a Worcester 4000 with a 10-year warranty and hassle free installation at a similar price via Heatable. Essentially, you’re getting 3 years extra warranty for free!

Boiler Controls and Accessories

The Ideal Logic C30 offers plenty of tools for excellent energy savings — we’ve listed them below.

24 Hour Mechanical Timer

Ideal Logic Plus 30kW combi boiler comes with a 24 hour mechanical timer — a simple but functional plug-and-play option.

Radio Frequency Electronic Programmer

This 7-day programmer is simple to use, but has some complex features, too. Users can control both the heating and hot water from a single dashboard.

Other features include the holiday mode, and the ability to set the boiler to pre-heat at a certain time.

Outdoor Sensor

This cool little product will monitor the outdoor air temperature around your property. As the temperature changes, it will adjust the flow water temperature. This way, your heating will be perfectly balanced at all time.

Tests have shown that an outdoor sensor has managed to improve efficiency by around 2%.

Flues and Flue Accessories

Like all boiler brands, Idea offer vertical and standard flues and flue accessories. If your flue is close to a neighbours’ (or your own) window, you can utilise Ideal’s plume management kit, which allows the installer to extend the flue.

Specification for Ideal Boilers

For the 30kW Logic Plus boiler, the most important specifications are:

• 30.3kW domestic hot water output
• 24.2kW central heating output
• 12.4L per minute flow rate
• The Logic 30kW & 35kW come with an LPG conversion kit (the 24kW model does not)

Our Verdict on the Logic Plus Range of Boilers From Ideal

The whole Ideal Logic Plus range of boilers offers excellent value for money. Our experience from supplying and installing this range has been extremely positive.

It used to be that the Ideal Logic Plus was the favourable option in comparison to the Worcester 30i combi, mainly due to the price. However, since Worcester Bosch supply their boilers to Heatable at discount rates, Worcester Bosch boiler installation is available cheaper than ever before.

So, we’d be heading straight for the Worcester 4000, with up to a 10-year warranty from Heatable.

Still set on buying an Ideal Logic Plus boiler? You’ll get a 7-year warranty, with prices comparable to the 4000, and can get quotes from either Heatable or local installers using this form.
