Intergas Xtreme 36 Combi Gas boiler frequently asked questions

Is the Intergas Xtreme 36 a system boiler, a combi boiler or a regular boiler?

If you are considering installing a combi boiler in your house or flat, then the Intergas Xtreme 36 boiler is certainly worth investigating.

Traditional boilers consist of one or more large tanks that take up a lot of space in people's homes. One tank heats water and keeps it warm and the other stores water for heating later.

In contrast, a combi boiler is a much smaller stand-alone unit. Instead of requiring water tanks, it draws cold water from the mains. When hot water is needed for a shower, for the washing up, or the dishwasher, the cold water is heated instantly by the boiler and distributed to where it is needed.

The main disadvantage of combi boilers is that there is a limit to how much water they are capable of heating at the same time. For instance, water pressure, volume and temperature will be adversely affected if more than one individual in the home needs hot water at the same time.

Is the Intergas Xtreme 36 combi boiler suitable 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.

Boiler output is measured in kilowatts and tells you how much power a boiler can use to heat the water your taps, showers and radiators need. The higher the output, the more power it has.

When choosing a boiler, you should choose one that can cope with the peak demand for hot water in your home and not just your typical usage.

If its output is too low, sometimes your hot water will not be hot enough, but if your boiler's output is too high for your needs, your gas bills will go up and not down.

The output of the Intergas Xtreme 36 combi is 27 kW, so which types of property would this Intergas Xtreme 36 Combi boiler be an appropriate choice for?

A PlumbProud Gas Safe engineer would recommend that the most suitable type of property for a Intergas Xtreme 36 combi would be smaller homes and apartments containing up to 10 radiators and providing hot water for one bathroom.

The Intergas Xtreme 36 is a combi boiler, which that means that you need to take the flow rate (measured in litres per minute) into account as well as the output rate. This Intergas Xtreme 36 Combi boiler's flow rate is 20 L/m.

Combis draw water from the mains, instantly heating and distributing it where it's needed - taps, radiators, bathrooms, and so on.

However, this means that the flow rate of a boiler may effectively be capped by the flow rate of the mains water supply. For example, if your mains pressure is 12l/m, that is the maximum flow rate that your boiler can achieve even if you choose a boiler with a flow rate of 18l/m.

In addition, if your home has more than one bathroom, a high number of radiators, and more than one member of your household wants to use hot water at the same time regularly, the flow rate of both the boiler and the mains water pressure may not be high enough.

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 Intergas Xtreme 36

The dimensions of the Intergas Xtreme 36 are TBC mm [H] x TBC mm [W] x TBC mm [D].

Intergas Xtreme 36 – non-condensing or condensing?

Condensing boilers convert the warmth present in flue exhaust gases and water vapour condensation into heat which they then recycle to increase the temperature of the colder water returning to your system.

We recommend that homeowners choose a condensing boiler like the Intergas Xtreme 36 for this reason - the more recent your model the better because the technology improves every year.

You'll benefit from lower quarterly gas bills and condensing boilers are also much more environmentally friendly.

Is the Intergas Xtreme 36 combi a good choice for the environment?

How we heat our homes and the effect that has on climate change has become important to many homeowners worried about the environment.

With central heating being responsible for 14% of greenhouse gas emissions in the UK, your choice of boiler matters. Gas boilers are also responsible for the significant atmospheric volumes of dangerous nitrogen dioxide emissions in larger British cities.

If you would like your next boiler to help in the fight against climate change, would the Intergas Xtreme 36 combi be a suitable choice?

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 Intergas Xtreme 36 was given an efficiency rating of 93% 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 ERP, short for the Energy Related Products Directive, is a European directive aimed at encouraging manufacturers to create products that are environmentally friendlier at all stages, including during manufacturing, when the product is in active use, right through to the point of final disposal.

The Intergas Xtreme 36 has a rating of "A" for heat and "A" for hot water production.

If the Intergas Xtreme 36 combi boiler breaks down, am I covered?

A parts and labour warranty of 7 years is included when you purchase the Intergas Xtreme 36 boiler through PlumbProud.

Intergas Xtreme 36 Combi Gas boiler frequently asked questions

What type of boiler is Intergas’s Xtreme 36 - system, regular or combi?

The Intergas Xtreme 36 boiler is an option you may wish to consider if you're looking for a combi boiler for your house or flat.

Traditional boilers often have up to two tanks that either store heated water or water to be heated later. Boiler manufacturers introduced combi boilers in the 1970s to avoid the need for those big tanks. Combi boilers allow homeowners to benefit from the reliable central heating and hot water level they want but without having to give up so much space within their properties - remember that homes in the UK are among the smallest in the developed world.

Your taps and radiators get the hot water they need with a combi boiler. Combi boilers draw cold water direct from the mains which is then heated instantly on demand and distributed to your radiators and taps.

However, combi boilers cannot heat very large volumes of water, which is their main disadvantage. So, for example, when someone wants to take a shower while another person wants to use a hot water tap to do the dishes, water pressure and quantity to both points decreases.

Should I install a Intergas Xtreme 36 combi boiler in my home?

It's best to choose a boiler whose size or "output" is right for your property. With a boiler, however, size does not mean how big the boiler is, it means how much power it has.

The amount of hot water you get from showers, bathrooms, and sinks and heat from your radiators depends on your boiler's output (measured in kilowatts). The higher the level of output, the better your home will be heated and you can be more certain that the water from your taps will be as hot as you want.

However, you must be careful. You might not get the hot water you want if your boiler output is too low. If it's too high, you'll be paying more than you need to for gas.

With the Intergas Xtreme 36 combi's output at 27 kW, which types of property would this Intergas Xtreme 36 Combi boiler be most appropriate for?

An experienced Gas Safe engineer would be likely to recommend that this Intergas Xtreme 36 Combi boiler is capable of providing heating and hot water to up to 10 radiators and one bathroom and would therefore be most suitable for smaller homes and apartments.

With combi boilers, you need to consider the flow rate as well as the output rate. The flow rate (shown in litres per minute) measures how much water your boiler can draw from the mains which it then instantly heats and distributes to your taps and radiators.

However, a high flow rate is of little to no value if your local water pressure is low. If your local mains water pressure is 10l/m and your flow rate is 12l/m, your boiler will only be able to process 10l/m.

If you live in an area with high water pressure but your household has multiple bathrooms and/or radiators and many members of your household want to use hot water at the same time (like morning or evening baths or showers), it's unlikely that you'll be able to find a combi with a high enough flow rate.

As an indication, a power shower needs about 10 litres of water per minute, whereas the flow rate of this Intergas Xtreme 36 Combi boiler is 20 L/ml/m.

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 is the size of the Intergas Xtreme 36?

The Intergas Xtreme 36's dimensions are TBC mm [H] x TBC mm [W] x TBC mm [D].

Intergas Xtreme 36 – condensing or non-condensing?

Condensing boilers like the Intergas Xtreme 36 improve energy efficiency and reduce your annual expenditure on gas.

They do this by capturing and recycling the warmth still present in water vapour condensation and flue exhaust gases to, for example, increase the temperature of the colder water returning from your radiators.

Condensing boilers are also much better for the environment because they emit fewer greenhouse gases.

Is the Intergas Xtreme 36 combi boiler good for the environment?

How we heat our homes has become a major issue for many people worried about climate change and environmental issues in general.

Around 14% of the greenhouse gases produced in the UK is a result of our central heating systems. Gas boilers are responsible for dangerous levels of nitrogen dioxide emissions in some of our largest cities.

Do the figures suggest that installing the Intergas Xtreme 36 combi at your property would help in the fight against climate change?

An energy efficiency rating of 92% or above is a legal requirement for all boilers manufactured and installed in the UK today. 92% is equivalent to a low-to-middle "A" grade on the "Seasonal Efficiency of Domestic Boilers" (SEDBUK) scale.

Energy efficiency measures how much energy a boiler uses and wastes in the course of its normal operation. The lower the waste, the lower your gas bills.

The Intergas Xtreme 36 was awarded an efficiency rating of "93%", equivalent to a "A" rating on the SEDBUK system.

The Energy Related Products Directive, also known as ERP, is European legislation that intends to reduce energy consumption related to products right from the initial manufacturing process through to eventual final disposal.

The purpose of the directive is to encourage manufacturers to create new products that are kinder to the environment and which result in lower overall harmful gas emissions through a product's entire life cycle.

The Intergas Xtreme 36 has a rating of "A" for heat and "A" for water.

What warranty do I get if I purchase the Intergas Xtreme 36 boiler?

The parts and labour warranty offered with this Intergas Xtreme 36 Combi boiler covers you for 7 years.
