Ease of installation

First things first, let’s talk about the easy installation process.

A new boiler from most brands will require a village for you to move it from the delivery truck to either your single bathroom unit or kitchen area.

Luckily, the Ideal Logic Combi C30 consists of the following dimensions, making it easy to install and maintain for the most part.

  • Depth: 278mm
  • Height: 700 mm
  • Width: 395 mm
  • Weight: 33.8 kg

Let’s take a look at more of the Logic C30’s specifications.

The average size of Ideal logic C30 is 700mm. Width: 395mm. Depth: 278mm.

This new boiler is compact enough to fit in a kitchen cupboard and is easy on the eye.

It also offers different flue options for what suits your property the best.

Best suited to 1 to 4 bedroom home:

Yes, the Ideal 30 kW combi boiler would be well suited.

The Ideal Logic 30 boiler range also includes output ratings of 24 kW for smaller homes and a 35kW boiler for larger homes.

Combination boilers heat hot water on demand, so the output on flow rates is extremely important (POWER).

Your engineer will be able to help advise which kW will suit your needs the most.

Ideal also offers combi, regular and system boilers.

Regular and system boilers are usually used in large homes with more space. They require a hot water cylinder as they don’t heat water on demand, therefore take up more space.

Customizable controls

A fully installed natural gas boiler is a great start, but it doesn’t take you to the finish line just yet.

The next step for you to fully grasp the Combi boiler is mastering the controls. Unlike other ideal boilers, you have full control of the heating settings.

Basically, you can calibrate and tinker around with your brand new boiler! Allow us to show you the different sensors before you get the fun started.

Ideal Logic C30 Combi Boiler review - A buyers guide Compare Boiler Quotes
  • Electronic programmer: It lets you create a 7-day schedule to help you organize the boiler’s active periods.
  • Outdoor sensor: It keeps an eye on the outer temperature of your water, thus increasing the efficiency rating by 2 per cent.

Indeed, these sensors enable your Ideal Logic Combi boiler to give you hot water according to your personal settings and overall preference.

You won’t have to worry about getting exposed to scorching temperatures unexpectedly costing you a fortune.

Be ready for a perfectly warm shower that massages the skin and releases all the tension in your body after a long day at work.

Alright, that’s enough ASMR (Autonomous Sensory Meridian Response) for now.

Is the Ideal Logic C30 energy efficient?

As we discussed a while ago, the Ideal Logic C30 boiler is part of the ErP (Energy-related Products) group, and rightfully so.

The boiler boasts of an impressive A rating when it comes to hot water and heating purposes. This is thanks in large part to its superior 94% energy efficiency rating. [R]

Older boilers cannot relate because some of them possess 70 per cent or below efficiency ratings. The Logic combi boiler is one of the most energy-efficient boilers in the UK

Buying a new boiler may sound expensive at first, but just imagine how much money and energy you are saving should you go for an A-rated Combi boiler.

You’ll be doing both your house and yourself a favour in the long run by getting the best combi boiler on the market.

Sufficient Heating for Everyone

Like most Ideal Logic boilers, the C30 model provides enough hot water and heating necessities for everyone!

Take a look at these numbers to see why this is such.

  • Maximum heat output: 24.2 kW (Kilowatts)
  • Maximum hot water output: 30.3 kW (Kilowatts)

These outputs are more than capable of covering small to medium-sized residential homes with 1-2 bathroom units.

If you’re a newlywed or planning to move out, this boiler is one of the first home appliances you should get!

Maximum Protection From Freezing

The primary function of all ideal logic combi boilers is to produce hot water. Early signs of freezing might negatively affect your boiler.

Some boilers cannot survive the cold winter months, thus resulting in some components such as the condensate pipe freezing.

Fortunately, the C30 boiler completely avoids this situation!

Its built-in frost protection ensures you still get your much-needed hot shower amidst the blistering cold outside your homeHow so?

Ideal Logic C30 Combi Boiler review

If the boiler notices that the temperature outside is at around 8 degrees Celsius or lower, the pump will circulate warm water to avoid freezing.

Excellent Repair and Warranty Service

Are you still not yet sold by the many cool features the Ideal Logic C30 boiler brings to the table?

This last benefit we are about to share should deliver the knockout punch against its boiler counterparts.

Other brands may hand out 1-2 year warranty periods like candy, but Ideal Heating takes their customer service to another level. [R]

It initially offers a standard 2-year warranty, but you can extend the Ideal warranty duration for as long as 5 or 10 years!

This is a major game-changer because you won’t have to spend on extra maintenance and repair services.

However, you need to make sure you avail of the warranty ASAP (30 days after your purchase to be exact)!

Compare alternatives to the Logic C30 combi

How does Ideal Logic C30 fare against its competitors? Let’s find out!

  • Heating Output: 24 kW
  • How Water Output: 30 kW

If you want to save a little more, we suggest sticking to the C30 model!

Both models are compact in size, with the Viessmann boiler having a height of 707 mm, only 7 mm more than the Ideal Logic C30.
