Ideal Logic+ C35 Combi Gas boiler frequently asked questions

Is the Ideal Logic+ C35 a combi, system or regular boiler?

If you’re looking for a combi boiler for your house or flat, then the Ideal Logic+ C35 is one you may wish to consider.

One of the reasons the combi boiler was introduced to Britain in the 1970s was because residential properties are among the smallest in the world. More traditional boilers require one or more large tanks to be stored around the home to function.

A combi boiler is a self-contained unit that draws water from the mains then heats and distributes it instantly and on demand - no tanks are needed.

They are the most popular type of boilers in the UK and offer only one major disadvantage - there is a maximum volume of water that can be heated at any one time. If that limit is exceeded by, for example, two people using a hot water tap at the same time, there will be a drop in water pressure, temperature and volume to both taps.

Should I install a Ideal Logic+ C35 combi boiler in my house or apartment?

Whether this Ideal Logic+ C35 Combi boiler is right for where you live depends on its size or "output" level. Size does not mean its physical dimensions - it means how powerful it is.

A boiler’s output is a measurement of the amount of power it can use to provide hot water to your taps and radiators. The higher its output rate, the more water it can heat.

If your new boiler’s output is too low, your hot water might not be as hot as you want it to be. If it's too high, you’ll be paying more for gas than you need to.

The output of the Ideal Logic+ C35 combi boiler is 35.3 kW, so which types of property would this be appropriate for?

Most heating engineers would recommend that this Ideal Logic+ C35 Combi boiler would be suitable for larger properties including detached homes with 15 or more radiators and two or more bathrooms.

If you are thinking about installing a combi boiler like the Ideal Logic+ C35 in your home, you should consider flow rates as well as output rates. This Ideal Logic+ C35 Combi boiler's flow rate is 15 L/m.

The flow rate indicates the maximum volume of water (measured in litres per minute) that your boiler can heat up and send to your radiators, taps and showers at any one time. The more taps and showers that could be in use simultaneously or the greater the number of radiators you have, the higher the flow rate you need.

However, you should establish what the mains pressure is at your property as a combi boiler can only heat the water that comes into your home.

For example, if your mains pressure is 12 litres per minute, your boiler can only heat and distribute hot water at a rate of 12 litres per minute even if it has a higher flow rate capacity. Typically, a power shower will require 10 litres of water per minute.

When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead if your family's demand for hot water is higher than normal.


What are the dimensions of the Ideal Logic+ C35 boiler?

The Ideal Logic+ C35 is 700 mm tall, 395 mm wide, and 278 mm deep.

Is the Ideal Logic+ C35 non-condensing or condensing?

The Ideal Logic+ C35 is a condensing gas boiler - this is the type of boiler we recommend to most clients because they're better for the environment and they will save money on annual fuel bills.

A condensing boiler captures and recycles the warmth still present in both the flue exhaust gases and water vapour condensation created when gas is burned to provide your boiler with power.

This means it needs less gas to operate and it uses this extra energy to perform a number of tasks, including heating the colder water that comes back to the boiler from the radiators in your home.

What energy efficiency ratings have been awarded to the Ideal Logic+ C35 combi?

With growing concern among the public about accelerating climate change, how we heat our homes and the impact this has on the environment has become a major topic of concern for many homeowners.

About 14% of the greenhouse gases we produce in the UK come from the power needed for central heating. In bigger British cities, gas boilers are a significant source of nitrogen dioxide emissions.

Is the Ideal Logic+ C35 combi an environmentally friendly choice for your home? Let’s have a look at the figures.

By law, the minimum level of energy efficiency for boilers manufactured in the UK is 92%, equivalent to a good SEDBUK “A” rating. Prior to April 2018, the minimum was 88% - boilers whose energy efficiency levels were 88% or 89% were given a "B" rating on the SEDBUK scale and those at 90% or higher were given an "A".

The energy efficiency rating awarded to each boiler indicates the amount of energy that is wasted when in operation.

Following testing, the Ideal Logic+ C35 was given a 94% energy efficiency rating and a SEDBUK grading of "A".

The Energy Related Products (ERP) directive is Europe-wide legislation designed to reduce harmful gas emissions at all points of a product's life cycle - from the production process to its actual end use, right through to final disposal.

The Ideal Logic+ C35 has a rating of "A" for heat and "A" for water.

What is the warranty period on a Ideal Logic+ C35 combi boiler?

The Ideal Logic+ C35 boiler comes with a parts and labour warranty of 7 years.

Ideal Logic+ C35 Combi Gas boiler frequently asked questions

Is the Ideal Logic+ C35 boiler a combi, regular or a system boiler?

Ideal’s Logic+ C35 is one you might consider if you’re looking for a combi boiler for your house or flat.

In the past, most boilers needed one or more storage tanks to operate - one to store warm water and the other for storing water to be heated later. But storage tanks are problematic in properties where space is at a premium and particularly where there is no loft. Many properties in the UK are small and so manufacturers introduced combi boilers in the 1970s to eliminate the need for tanks.

With a combi boiler, the hot water for your radiators and taps is delivered on demand. The boiler instantly heats water it draws directly from the mains internally. It then distributes the heated water around your home at mains pressure as you need it.

It is important to bear in mind that, while combi boilers have many benefits, they can only heat a certain volume of water at any given time. This means that, if you run a shower at the same time as someone else is doing the washing up in the kitchen, the volume of water passing to each point will drop, causing a fall in pressure.

Is the Ideal Logic+ C35 combi boiler the right choice for my house or apartment?

To determine that, we need to consider the size of the boiler. Size doesn't mean how big it is - it means how big its "output" is.

Your boiler's output indicates the maximum amount of power available to it to heat the water you need to warm your radiators or when you want hot water from your taps. A higher output rate means that your boiler is capable of heating greater volumes of water.

If a boiler's output rate is too low, you'll often find that the water is not as hot as you want it to be. Too high, however, and you'll end up paying more for your gas than you should be.

The Ideal Logic+ C35 combi boiler has an output rate of 35.3 kW, so which types of property would this be suitable for?

Most heating engineers would recommend that this Ideal Logic+ C35 Combi boiler would be suitable for larger properties including detached homes with 15 or more radiators and two or more bathrooms.

You should also consider a combi boiler's "flow rate" when making your choice.

The flow rate indicates how much water it can take from the mains supply at any one time (measured in litres per minute), which it then heats and distributes to different points in your home like your bathroom, kitchen and radiators. This Ideal Logic+ C35 Combi boiler's flow rate is 15 L/m.

Combi boilers have no storage tanks like system or heat only boilers. This means that if the water pressure where you live is low, there's no benefit in spending money on a combi with a high flow rate because a high flow rate doesn't mean it can draw any more water from the mains.

In addition, there might be lots of people in your household who want to use hot water at the same time while also having the central heating on. Given that average mains pressure in the UK is between 10 and 12 litres per second and a power shower usually requires about 12 litres of water per minute, a combi boiler might not be the right choice for you and your family.

When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead if your family's demand for hot water is higher than normal.


The size of the Ideal Logic+ C35 in millimetres

Ideal’s Logic+ C35 is 700 mm tall, 395 mm wide, and 278 mm deep.

Is the Ideal Logic+ C35 condensing or non-condensing?

The Ideal Logic+ C35 boiler is a condensing gas boiler and we recommend that you select one of the latest models if possible.

Condensing boilers reduce homeowners' gas bills and are better for the environment. They do this by capturing and recycling the heat still present in the flue exhaust gases and water vapour condensation produced when boilers burn gas to generate the power they need to operate.

What energy efficiency ratings have been awarded to the Ideal Logic+ C35 combi?

With environmental issues in the spotlight, more and more homeowners are becoming concerned about how they heat their homes and how much they're contributing towards combatting climate change.

14% of the total amount of greenhouse gases produced by the UK comes from the central heating systems we use. In some of Britain's biggest cities, gas boilers create dangerous levels of nitrogen dioxide in the atmosphere.

Is the Ideal Logic+ C35 combi boiler an environmentally friendly choice for your home? Here’s what the figures say.

By law, boilers manufactured and supplied in the UK must achieve a SEDBUK rating of "A" and work at a 92% minimum efficiency. Before April 2018, a minimum of 88% energy efficiency needed to be achieved (88/89% = SEDBUK "B" and 90% = SEDBUK "A").

Following official testing, the Ideal Logic+ C35 was given an efficiency rating of 94% with a SEDBUK rating of "A".

Energy efficiency is a measure of how much energy is used and how much is wasted when a boiler is operating.

The Energy Related Products Directive (ERP) intends to reduce the amount of energy consumed by individual products over their entire lifetime, from the initial manufacturing process to final disposal and at all points in between.

The legislation is designed to encourage manufacturers to create products that are more environmentally friendly and which result in a reduction in harmful gas emissions.

The ERP rating for the Ideal Logic+ C35 is "A" for heat and "A" for hot water production.

Will I be covered if the Ideal Logic+ C35 combi breaks down?

The parts and labour warranty on the Ideal Logic+ C35 covers all repair-related costs for 7 years while the heat exchange warranty covers you for [Heat Exchange Warranty] years.
