Heatrae Sadia Electromax 9kW Combi Electric boiler frequently asked questions

Is the Heatrae Sadia Electromax 9kW a standard, combi or system boiler?

When looking for a combi boiler for your house or flat, the Heatrae Sadia Electromax 9kW might be a suitable option for you.

Traditional boilers need one or more large tanks to work - one to heat and keep water warm for immediate use and the other to store water intended for heating later. Finding space for these large tanks is difficult in British residential property - remember that our houses and flats are among the smallest in the world. This is the problem that combi boilers were designed to solve when they were introduced in the 1970s.

Combi boilers don't need a tank - instead, they instantly heat water drawn from the mains using technology inside the boiler. This hot water is then distributed immediately to your taps or radiators on demand.

The biggest disadvantage to combi boilers is that they have a maximum capacity for heating water, meaning that they work best when only one point within a household wants hot water. For example, if someone is taking a shower and another person uses a hot water tap at the same time, the water pressure, volume and temperature to both points drops.

Is a Heatrae Sadia Electromax 9kW combi boiler appropriate 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 electric bills will go up and not down.

The output of the Heatrae Sadia Electromax 9kW combi is 9 kW, so which types of property would this Heatrae Sadia Electromax 9kW Combi boiler be an appropriate choice for?

A boiler engineer would recommend that, at this level of output, the most suitable type of property for this Heatrae Sadia Electromax 9kW Combi boiler would be smaller homes and apartments with up to 10 radiators and one bathroom.

With combi boilers, flow rates are as important a consideration as output rates.

All combi boilers draw water from the mains. They then heat this water instantly whenever it's needed and distribute it to your radiators and taps.

A boiler's "flow rate" describes how much water a boiler can draw from the mains at any one time, which it then heats and sends around your home (measured in litres per minute). This Heatrae Sadia Electromax 9kW Combi boiler's flow rate is TBCl/m.

If your home has a large number of radiators, a lot of bathrooms, or multiple people who wish to use the hot water at the same time, your combi boiler may not be able to draw as much water from the mains as it needs to serve everyone, regardless of how high the flow rate is.

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 Heatrae Sadia Electromax 9kW?

The dimensions of the Heatrae Sadia Electromax 9kW are 1,476 mm [H] x 550 mm [W] x 600 mm [D].

There are still hundreds of thousands of floor-standing boilers like the Heatrae Sadia Electromax 9kW throughout the UK even though compact, wall-mounted boilers have become the preferred choice for most homeowners in the last 20 years who want more space to live. It is still possible to replace your existing floor-standing boiler with a wall-mounted unit if you want but please keep in mind that the pipework might need to be replaced in addition to the boiler and installation.

You will eventually recover that investment with savings on your electric bills but this will take some time.

If you're considering replacing your existing heat only or system boiler with the Heatrae Sadia Electromax 9kW, you will also need to remove the hot water cylinder and/or expansion tank.

For information and guidance on the best course of action, please contact PlumbProud and we'll share our thoughts.

Electromax 9kW – non-condensing or condensing?

Electric boilers like the Heatrae Sadia Electromax 9kW are more economical in their fuel use than non-electric boilers. This is because electric boilers do not need to recycle the warmth contained in exhaust gases created from the burning of gas and oil, therefore they do not need to be modified to be condensing.

Is the combi Heatrae Sadia Electromax 9kW boiler energy efficient?

As more of us are increasingly concerned about climate change, how we heat our homes and its impact on the environment has become an issue of importance to homeowners.

We generate 14% of UK greenhouse gas emissions through centrally heating our domestic properties. Gas boilers are mainly responsible for harmful nitrogen dioxide emissions in larger British cities.

If you decide to install a Heatrae Sadia Electromax 9kW combi in your home, will you be helping the environment with your choice? Let’s have a look at the figures.

All boilers manufactured and supplied in the UK after April 2018 must achieve an "A" grade on the SEDBUK rating system as well as score a minimum of 92% on a separate energy efficiency test. Prior to that, the minimum was 88% - boilers rated at 88% and 89% were given a “B” rating (90% and higher were given an "A").

An energy efficiency rating describes how much energy the boiler uses and how much it wastes when in use.

The Heatrae Sadia Electromax 9kW was awarded an efficiency rating of 99.8% with a SEDBUK grading of "D".

The boiler's poor ERP rating however reflects the fact that it runs on electricity.

In 2015, the EU introduced the Energy Related Products Directive (ERP), the aim of which was to ensure that all manufacturers, including boiler manufacturers, developed more efficient products and processes.

The legislation aims to conserve energy at all life cycle stages, from initial production to the product's actual use by the customer, through to the point of disposal.

This Heatrae Sadia Electromax 9kW Combi boiler's ERP rating is "D".

How is this so given that electric boilers are nearly always more efficient than their gas and oil counterparts, with an actual operational efficiency rating around the 98% to 99% mark, in most cases? Some electric boilers receive very low ERP scores because the electricity they draw for power is often generated by burning fossil fuels. In our opinion, this is unfair on electric boilers.

How long is the warranty offered by the manufacturer for the Heatrae Sadia Electromax 9kW boiler?

On the Heatrae Sadia Electromax 9kW, the manufacturer offers a parts and labour warranty of 2 years.

Heatrae Sadia Electromax 9kW Combi Electric boiler frequently asked questions

Which category of boiler does the Heatrae Sadia Electromax 9kW fit into?

If you are considering installing a combi boiler in your house or flat, then the Heatrae Sadia Electromax 9kW boiler is certainly worth investigating.

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.

Is a Heatrae Sadia Electromax 9kW combi boiler suitable for my house or apartment?

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

A boiler’s output indicates the amount of power it can use when heating the water which it then sends to your taps and radiators. The higher the output rate, the more water it can heat.

If a boiler’s output is too low, there will be times when your hot water might not be as hot as you want it to be. If it is too high, you’ll likely be paying more than you need to for your gas.

Measured in kilowatts, the Heatrae Sadia Electromax 9kW combi's output level is 9 kW, so which types of property would this Heatrae Sadia Electromax 9kW Combi boiler be an appropriate choice for?

An experienced PlumbProud boiler engineer would likely recommend this Heatrae Sadia Electromax 9kW Combi boiler as suitable for smaller homes and apartments with up to 10 radiators and one bathroom.

If you are considering installing a combi boiler in your home, you need to consider the flow rate as well as the output rate.

The flow rate is the volume of water (measured in litres per minute) that your boiler can instantly heat up and send around the home. The more demand in your home for water at the same time (for example, two people taking showers in different bathrooms), the higher the flow rate you'll need.

However, the actual flow rate your boiler can deliver is also determined by your mains water pressure. If you choose a boiler with a flow rate of 16l/m but the mains water pressure is 12l/m, your boiler will only perform to 12l/m. This Heatrae Sadia Electromax 9kW Combi boiler's flow rate is TBCl/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.


Heatrae Sadia Electromax 9kW dimensions

Heatrae Sadia’s Electromax 9kW is 1,476 mm tall, 550 mm wide, and 600 mm deep.

Floor-standing boilers can still be found in hundreds of thousands of properties in the UK - however, many homeowners are considering switching to wall-mounted units to create new living space for themselves and their families. Our engineers can replace your current floor-standing unit with a wall-mounted model, although please be aware that we may need to charge more if your current pipework needs replacing.

Your investment will be worth it as you'll more than cover the cost with the saving you make every year on your electric bills.

Please note that if you choose to replace your current system or heat only boiler with the Heatrae Sadia Electromax 9kW, we'll also need to remove your hot water cylinder and/or expansion tank.

Should you require help, please contact PlumbProud as we would be happy to provide guidance.

Is the Heatrae Sadia Electromax 9kW condensing or non-condensing?

Electric boilers like the Heatrae Sadia Electromax 9kW don't need to be "condensing", unlike gas and oil boilers. That's because, unlike gas and oil boilers, electric boilers do not burn any fuel which creates still-warm exhaust gases that condensing boilers then use to, among other tasks, heat water coming back from your radiators. They are, by design, more efficient in operation than non-electric boilers and they're not covered by the 2005 law requiring all boilers to be "condensing".

Is the Heatrae Sadia Electromax 9kW combi an energy-efficient boiler?

As more of us are increasingly concerned about climate change, how we heat our homes and its impact on the environment has become an issue of importance to homeowners.

Central heating systems are responsible for 14% of greenhouse gas emissions in the UK. You may also be aware that the gas boilers we use emit dangerous nitrogen dioxide in large volumes in the bigger British cities.

Would choosing the Heatrae Sadia Electromax 9kW combi boiler be an environmentally friendly decision? Here's what the figures say.

All boilers manufactured and supplied in the UK after April 2018 must achieve an "A" grade on the SEDBUK rating system as well as score a minimum of 92% on a separate energy efficiency test. Prior to that, the minimum was 88% - boilers rated at 88% and 89% were given a “B” rating (90% and higher were given an "A").

An energy efficiency rating describes how much energy the boiler uses and how much it wastes when in use.

The Heatrae Sadia Electromax 9kW was awarded an efficiency rating of 99.8% with a SEDBUK grading of "D".

The ERP ratings of this Heatrae Sadia Electromax 9kW Combi boiler are however marked down because it's powered by electricity.

The Energy Related Products Directive grades products according to the energy they consume and the harmful gas emissions they create, from manufacturing right through to final disposal, including how they're used by customers between these two points.

The Heatrae Sadia Electromax 9kW has been graded "D" by ERP assessors.

Some electric boilers receive lower ERP scores because of the carbon emissions created by the burning of fossil fuels to generate the electricity they use for power. This is unfair because the actual operational energy efficiency of most electric boilers is either 98% or 99% - a level that no oil or gas boiler has yet reached.

Will I be covered if the Heatrae Sadia Electromax 9kW combi breaks down?

Heatrae Sadia’s Electromax 9kW boiler includes a parts and labour warranty of 2 years.
