Ideal Logic Plus 24 kW Boiler (Review): Features, Prices & Warranty of the Ideal Logic+ Combi 24

If you’re leaning towards an Ideal Heating boiler and the 24kW is something that will suit your house, we ran an Ideal Logic+ 24 review so that you’re in the know before purchasing one.

Here, we’ll provide a thorough overview of the Ideal Logic Plus 24 kW combination boiler, its warranty, features, prices and alternatives.

Are Ideal Logic Boilers Any Good? (Ideal Logic Combi 24+ Review)

Yes — Ideal boilers are an excellent brand. In fact, they’re hot on the heels of the Worcester Bosch Greenstar range, mainly due to their generous, 7-year warranty, attractive price point.

Ideal Heating boilers have been getting more and more popular, and now manufacture over 24,000 boilers per month.

Ideal Logic vs. Logic Plus

It’s important not to confuse Ideal Logic 24 with the Ideal Logic Plus 24 combi boiler.

Idea Logic is the standard range (sometimes branded as the Ideal Instinct 24), it’s cheaper, and only comes with a 2-year warranty.

On the other hand, Ideal Logic Plus is one down from the Idea’s flagship range, the Vogue. And, Logic Plus comes with an extended, 7-year warranty.

The price difference between the Ideal Logic 24 and Logic Plus 24 combi boilers is relatively small, around £200. So, by purchasing the Logic Plus 24 combi boiler, you’re essentially paying just £40 per extra year of warranty. And that’s well worth the money when you consider the installation could cost upwards of £2,000.

Again, the alternative here is to get a Worcester Bosch Greenstar 4000 25kW, at a similar price, but with a 10-year warranty. You can check prices using this online form.

Price Difference: Ideal Logic Plus 24 vs Worcester Greenstar 25i

The Worcester Bosch Greenstar 25i is the equivalent of the Logic combi boiler; you can see our review of the 25i here.

The first cost consideration is the boiler itself. And you can expect to pay around £750-800 for an Ideal Logic combi 24 (boiler only). The Worcester 25i is likely to set your back around £900-950, so £150-200 more.

However, to get the top warranty on a Worcester boiler, you’ll need to use their controls and magnetic system filter. These items, combined, are likely to cost £100 more than controls from Honeywell and filters from Fernox or Magnaclean (all good brands).

And, it goes without saying, you’ll need to use Worcester’s flue kits. A vertical flue and multiple extensions could increase the boiler fitting cost by another £100 or even more.

Also, keep in mind that installers typically like installing Ideal boilers, and price their installation accordingly. Why? Because their installation is straightforward — Ideal boasts several flueing options, includes a PRV wall outlet pipe, has preformed copper tails, and a relatively low lift weight.

Long story short, a Worcester 25i is going to cost around £350-400 more than an Ideal Logic Plus 24.

How to Find a Good Deal on a Worcester Boiler

However, you may be able to get a better deal on the Worcester 25i, or even its successor — the Greenstar 4000 25kW — by using Heatable. They’re an online installation company who fits tonnes of Worcester boilers, and consequently, get awesome wholesale deals from Worcester Bosch.

Features of the Ideal Logic Plus 24

Now, let’s see what the Ideal Logic C24 combi boiler has to offer.

Firstly, know that Ideal do an excellent job of giving their boilers a user-friendly control panel. Incorporating a backlit display  is a prime example. This feature makes it easy to see any fault codes, the boiler pressure gauge, and it even has a built-in service reminder that ensures your boiler is always looked after.

And, if you live off the natural gas grid, you’ll be happy to know that the Ideal Logic Plus 24 comes with an LPG conversion kit.

Ideal Logic Plus 24 Frost Protection

If there’s one boiler feature you should care about, it’s the boiler frost protection.

In the winter, a lot of boilers (from all brands) suffer from issues caused by a frozen condensate pipe. Condensate pipes and pumps are prone to freezing up during cold weather, and this often causes the boiler to lock out. When such a lockout happens, you have to either manually thaw the frozen pipe, or call a heating engineer to solve the problem for you.

Ideal have incorporated frost protection into all Logic Plus boilers, which means you shouldn’t get lockouts, or need to call an engineer because your boiler stopped working on a frigid winter morning.

Ideal Controls and Accessories

Below, we’ll walk you through the controls and accessories you’ll be getting with an Ideal Logic Plus 24.

24-Hour Mechanical Timer

The Logic Plus 24 comes with a built-in mechanical timer. It’s simple but effective. That said, the boiler can still be paired with a range of room thermostats as well.

Ideal RF Programmer

If you are looking for something with a bit more function to it, the RF programmer is a good option. The RF programmer allows users to work on a 7 day schedule and incorporates holiday mode and pre-heat.

External Sensors

Ideal Boilers have developed what they call the “outdoor boiler sensor.” This means your heating won’t just be monitoring the air temperature inside your property, but also the air outside. It will use both temperatures to automatically adjust the temperature of the water flowing around your central heating system.

Tests have proven that this sensor can improve efficiency by as much as 2%. Also, note that this combi boiler is endorsed by the Energy Saving Trust and has an ErP A rating, which means that it’s highly efficient already and you needn’t worry about overspending on your energy bills (in fact, you might see some energy savings by upgrading to this model from an old boiler).

Optional Plume Management Kit

The most important flue accessory is the plume management kit. These are used when the flue gases are released too close to windows (usually above the flue). The plume management kit allows you to direct the gases in whatever direction you want.

Compact Boiler Design

Worcester Bosch produce what’s known as a “Compact range.” It’s designed to fit into small spaces, such as kitchen cupboards. One problem — it’s more expensive.

The Ideal Logic Plus 24 combi boiler features a compact and stylish cupboard fit design. If you are looking to fit the boiler into a small space, check out the spec sheet below (direct from Ideal).

Logic Plus 24 Suitable Property Size

The Logic Plus 24 combi is the smallest Logic Plus there is in terms of heat output and flow rate, so Ideal recommend using these boilers in small properties. This means 1-2 bedroom apartments, and up to 2-bedroom terrace homes. And that’s only if there isn’t a huge demand for hot water and heating (i.e. around 10 radiators).

Realistically, however, we’ve been called out to service the Logic Plus 24 in 3-bedroom semidetached houses, and they never had any problems keeping up with the demand for heating and hot water.

That said, there is one scenario where an Logic Plus 30 is going to be a much better move; and that’s if you need to run 2 showers at the same time. The 30kW has a higher flow rate (12.4L/minute vs 9.9L/minute) and central heating output, so it should do a better job of supplying a high volume of water at once.

Now, if you consistently use a great deal of hot water, you should consider getting a different boiler type. Ideally, you’ll need a heating system setup that has a hot water cylinder and a system boiler.

Ideal Logic+ 7-Year Warranty

There’s no messing around with the Ideal Logic Plus parts and labour warranty. It’s 7 years, and you don’t have to fit their own branded controls or filters. What’s more, you get a 10-year warranty on the boiler’s heat exchanger — a great deal, since a heat exchanger typically costs an arm and a leg to replace.

Now, that’s a great warranty! Remember, though, you can also to get up to 10 years via Heatable if you’re buying a Worcester Bosch Greenstar 4000.

Ideal Plus 24kW Verdict

Overall, the Ideal Logic Plus 24kW is an excellent combi boiler, provided you have a smaller property and reasonable demand for hot water. It’s also a fantastic choice if you need a boiler to fit into a kitchen cupboard — a convenience that comes at a steep premium with most other brands. The Logic Plus 24 has a wide assortment of features, and its warranty gives you a solid 7 years of coverage.

    Would the Ideal Logic be good for a small shop with only two rads? It’s hard to know what boiler to get for such a small property.

    1. Alex Ion says:

      More than enough, I would say. But I guess it depends on the price. If you can get a Worcester for the price of an Ideal (see the Warmzilla links on our site) … I’d go for a Worcester instead.
