Product Description

Ideal Logic Max Combi² C35 35kW Combination Boiler

Part Number: 228336

Heat your home and enjoy instant hot water with the Ideal Logic Max Combi² C35 35kW Combination Boiler. This compact natural-gas boiler provides central heating and hot water from one unit. Therefore, it does not need a separate hot-water cylinder.

The C35 provides a maximum hot-water output of 35.3kW. In addition, it delivers up to 14.5 litres of hot water per minute at a 35°C rise. As a result, it offers the highest hot-water flow in the Logic Max Combi² range.

The package also includes a high-quality Ideal brass system filter. The filter collects magnetic debris from the heating water and helps protect the boiler. Therefore, it can support the long-term health of the heating system.

Furthermore, the boiler measures only 700mm high, 395mm wide and 278mm deep. Its compact size makes it suitable for many standard kitchen cupboards.

Warranty: Ideal supplies the Logic Max Combi² with a ten-year parts and labour warranty when registered within 30 days of installation. Ideal’s installation, registration and servicing conditions apply.

Heating and Hot-Water Performance

The Ideal Logic Max C35 heats water when you open a hot tap. Therefore, you do not need to store hot water in a separate cylinder.

The boiler provides a maximum hot-water output of 35.3kW. In addition, it can deliver up to 14.5 litres of hot water per minute at a 35°C rise.

This higher hot-water flow makes the C35 a useful choice for homes with greater hot-water demand. For example, it can help fill a bath faster than the C24 and C30 models.

However, actual performance depends on the incoming water pressure, flow and temperature. Therefore, ask an installer to test the mains-water supply before ordering.

Central-Heating Output

Although the C35 carries a 35kW rating, that figure mainly refers to its hot-water output. The boiler provides up to 24.2kW for central heating at a 70°C mean water temperature.

Therefore, the installer must check both the heating load and hot-water needs of the property. The engineer should consider the number of radiators, insulation levels and size of the home.

Is the Ideal Logic Max C35 Suitable for My Home?

The C35 suits homes that need a higher flow of hot water from a combi boiler. Therefore, it may suit properties with a larger bath, high-flow shower or greater daily hot-water use.

However, a combi boiler supplies hot water directly from the incoming mains. As a result, low mains pressure or flow can limit its performance.

A Gas Safe registered engineer should check your water supply and heating needs before recommending this boiler.

Ideal System Filter Included

The Logic Max package includes a high-quality Ideal brass system filter. This filter catches magnetic dirt and other debris from the heating water.

As a result, the filter helps protect the boiler, pump and other heating parts. It may also help the system maintain a steady flow when the installer cleans and services it correctly.

The installer must fit the filter in the correct position and follow Ideal’s instructions. In addition, the filter will need regular cleaning during the annual boiler service.

Compact Cupboard-Fit Design

The Ideal Logic Max C35 measures 700mm high, 395mm wide and 278mm deep. Therefore, it can fit inside many standard kitchen cupboards and utility spaces.

The boiler also weighs only 28.6kg when ready for installation. As a result, it remains easier to lift and position than many larger boilers.

However, the engineer must still allow the installation and service clearances shown in the official instructions.

Simple Digital Controls

The large digital display allows the user to check the boiler status and change the heating or hot-water temperature. In addition, the front pressure gauge makes it easy to check the system pressure.

The boiler also provides useful service reminders and fault information. Therefore, the display can help both the homeowner and heating engineer.

Intelligent Hot-Water Preheat

The intelligent preheat function helps reduce the wait for hot water. As a result, the boiler can respond more quickly when you open a tap.

However, hot-water performance still depends on the incoming mains supply. Therefore, your installer should test the water pressure and flow rate before fitting the boiler.

Compatible Heating Controls

The Ideal Logic Max Combi² works with suitable Ideal Halo heating controls. These controls can provide more accurate time and temperature settings.

Some controls can also improve comfort and help reduce wasted energy. Therefore, ask your installer to choose a control that suits your home and meets current Boiler Plus requirements.

Ten-Year Ideal Warranty

The Ideal Logic Max Combi² C35 comes with a ten-year parts and labour warranty. However, Ideal’s current terms and conditions apply.

A Gas Safe registered engineer must install and commission the boiler. In addition, the boiler must be registered with Ideal within 30 days of installation.

You must also arrange a service every year. Therefore, keep your proof of purchase, registration details, Benchmark checklist and annual service records.

Installation Requirements

• Use a Gas Safe registered engineer
• Check the gas supply and working pressure
• Check the incoming mains-water pressure and flow rate
• Confirm that a sealed heating system is suitable
• Complete a system flush before installation
• Add suitable system treatment chemicals
• Fit and clean the included Ideal system filter
• Select a compatible Ideal flue separately
• Fit suitable heating controls
• Install the condensate drain correctly

A qualified engineer must install and commission this boiler. Therefore, do not attempt to fit, alter or commission it unless you hold the correct Gas Safe qualifications.

Check Before Ordering

• Confirm that the C35 model suits the property
• Check the incoming water pressure and flow rate
• Confirm that you require the natural-gas model
• Select a suitable Ideal flue kit
• Check whether the flue needs extensions or bends
• Choose a suitable heating control
• Check the boiler dimensions and service clearances
• Arrange installation with a Gas Safe registered engineer
