Heatrae Sadia Electromax 9kW Combi Electric boiler frequently asked questions

What type of boiler is the Heatrae Sadia Electromax 9kW - regular, system or combi?

The Heatrae Sadia Electromax 9kW is a combi boiler you may wish to consider if you want this particular type of boiler for your house or flat.

Traditional boilers have one or more large tanks in which they store either heated water or water to be heated later. Manufacturers originally introduced combi boilers to the market in the 1970s to enable homeowners to save space - UK residential properties are among the smallest in the Western world.

Combi boilers don't need these tanks because they draw water directly from the mains and instantly heat it on demand thanks to the technology inside the boiler. Combi boilers then distribute this hot water to your home’s taps and radiators when needed.

The most significant disadvantage of combi boilers is that they are not ideal in larger homes where multiple people might want hot water at the same time – for example, if someone is having a shower while another wants to wash dishes in the kitchen. This is because combi boilers have a maximum volume of water that they can heat. When two people want hot water at the same time, the water temperature, pressure and volume delivered to both points drop.

Should I install a Heatrae Sadia Electromax 9kW combi boiler in my house or apartment?

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

Your boiler’s output is a measurement of the power it has available to heat the volume of water required for your taps and radiators. The higher the output rate, the more water it can heat.

You need to be careful to select a boiler with the optimal level of output for your property though. That's because, if your boiler output is too low, your water and radiators will often not be as hot as you want them to be. If the output is too high, you’ll be paying more for electric than you need to.

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 appropriate for?

An experienced PlumbProud heating engineer would recommend that the level of output from this Heatrae Sadia Electromax 9kW Combi boiler would make it a suitable installation option for smaller homes and apartments with up to 10 radiators and one bathroom.

Flow rates are important when choosing a combi boiler as well as output rates.

A combi boiler's flow rate (measured in litres per minute) describes how much water it can instantly heat then distribute to the taps and radiators in your home - you will need to factor this into your decision on a new combi boiler. This Heatrae Sadia Electromax 9kW Combi boiler's flow rate is TBCl/m.

If you have a lot of radiators and bathrooms in your home and there's lots of demand within your household for hot water at the same time (like morning or evening showers and baths), you'll need a boiler with a high flow rate.

However, it's not quite that simple. If your local mains water pressure is low, you're not going to gain any benefit from choosing a combi boiler with a high flow rate because that higher flow rate doesn't mean it can draw more water from the mains pipes.
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 Heatrae Sadia Electromax 9kW boiler?

The Heatrae Sadia Electromax 9kW measures 1,476 mm high and 550 mm wide by a depth of 600 mm.

Wall-hung boilers have been the most popular installation choice over the last 20 years because they're compact, discreet, and don’t take up much space. Yet there are still hundreds of thousands of UK homeowners whose central heating is provided by floor-standing boilers like the Heatrae Sadia Electromax 9kW, which they're looking to replace to free up more living space. This is possible, however please be aware that there may be an additional cost if we need to replace your existing pipework.

That said, you should be able to fully recoup your investment within a few years thanks to the quarterly savings you'll make on your electric bills.

Replacing an existing heat only or system boiler with the Heatrae Sadia Electromax 9kW will also require our fitters to remove and dispose of your hot water cylinder/expansion tank.

Please contact PlumbProud for more information and guidance on the right course of action for you.

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

Electric boilers like the Heatrae Sadia Electromax 9kW do not produce exhaust gases, unlike gas and oil boilers, meaning that they do not need to be adapted to be "condensing". For a gas or oil boiler to be condensing, it must have a secondary heat exchanger that recycles the warmth present in exhaust gases to reheat water coming back from the radiators.

Is the Heatrae Sadia Electromax 9kW combi rated as environmentally friendly?

As more of us become concerned by the effects of climate change, the damage we do to the environment by heating our homes has emerged as an important issue for many homeowners.

Central heating produces 14% of all greenhouse gas emissions in the UK. Gas boilers in the larger cities emit dangerous levels of nitrogen dioxide.

Would choosing the Heatrae Sadia Electromax 9kW combi be an environmentally-friendly choice? If so, let's look at its performance figures.

All boilers manufactured and supplied in the UK are assigned two energy efficiency ratings. By law, they must achieve a SEDBUK "A" rating subject to a minimum efficiency level of 92%. Prior to 2018, the minimum was 88% (88% and 89% are equivalent to a SEDBUK "B" grade and 90% and above an "A" grade).

The rating awarded to the Heatrae Sadia Electromax 9kW is 99.8% with a SEDBUK rating of "D".

But because it's powered by electricity, it is penalised in its ERP ratings.

The Energy Related Products Directive (ERP) aims 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 Heatrae Sadia Electromax 9kW is "D".

This Heatrae Sadia Electromax 9kW Combi boiler’s ERP rating is particularly low despite the fact that the actual operating energy efficiency of electric boilers like these is generally 98% or 99% - better than even the most efficient gas or oil boiler. The reason it's marked down is that the electricity needed to power the boiler is generated by burning fossil fuels, which is considered carbon-intensive - we're not sure that's a fair comparison at PlumbProud.

What warranty do I get if I purchase the Heatrae Sadia Electromax 9kW boiler?

The Heatrae Sadia Electromax 9kW boiler is covered by 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.

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 Heatrae Sadia Electromax 9kW combi boiler a suitable option for my house or flat?

It's best to choose a boiler whose size or "output" is right for your home.

The more hot water and heat you want, the higher the output level of your boiler should be. Output is measured in kilowatts and it describes the maximum level of power your boiler has to heat water.

If your output level is too low, your boiler will not have the power it needs to get your water as hot as you want it, particularly when there's a lot of demand for it. Choose a boiler whose output level is too high and you'll have all the hot water you need but will be paying too much for it through higher electric bills.

Which types of property would this Heatrae Sadia Electromax 9kW Combi boiler be appropriate for given its output of 9 kW?

A PlumbProud Gas Safe engineer would recommend that the most suitable type of property for a Heatrae Sadia Electromax 9kW combi would be smaller homes and apartments containing up to 10 radiators and providing hot water for one bathroom.

In addition to the output rate, you should consider a boiler's "flow rate" (measured in litres per minute) when choosing a combi boiler.

If you have a lot of radiators and bathrooms in your home and members of your household want to use hot water at the same time (like morning or evening showers and baths), you'll need a boiler with a high flow rate. This Heatrae Sadia Electromax 9kW Combi boiler's flow rate is TBCl/m.

However, it's not that simple. Combis can only draw water from the mains at the speed it's delivered. Homes with higher than average demand for hot water, and particularly those in low mains pressure areas, may find that a combi boiler is not the right answer for them.

When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead to better serve you and your family.


What is the size of the Heatrae Sadia Electromax 9kW?

The measurements of the Heatrae Sadia Electromax 9kW are 1,476 mm by 550 mm by 600 mm.

Many homeowners still have floor-standing boilers like the Heatrae Sadia Electromax 9kW even though wall-mounted boilers have been the preferred choice because of their compact size. If you want to replace your existing boiler with a compact wall-hung one to free up extra living space for you and your family, we can do this for you but please be aware that we may need to replace much of your existing pipework, which will incur an additional charge.

However, given the efficiency of modern wall-mounted electric boilers, the savings you make on your energy bills over the coming years should more than repay the cost of your investment.

If you are considering replacing your current heat only or system boiler with the Heatrae Sadia Electromax 9kW, please be aware that this will involve removing your hot water cylinder and/or expansion tank.

For guidance and further information, please contact the team at PlumbProud who will be happy to help you make the right choice.

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

Electric boilers like the Heatrae Sadia Electromax 9kW do not produce exhaust gases, unlike gas and oil boilers, meaning they do not need to be adapted to be "condensing". For a gas or oil boiler to be condensing, it must have a secondary heat exchanger that recycles the warmth present in exhaust gases to reheat water coming back from the radiators.

How energy efficient is the Heatrae Sadia Electromax 9kW combi boiler?

As the British public has become more conscious of climate change, many homeowners consider the environment when choosing how to heat their homes.

Dangerous levels of nitrogen dioxide emissions in larger UK cities are caused by gas boilers in domestic properties, and 14% of the UK’s greenhouse gas production is as a result of central heating.

Would choosing the Heatrae Sadia Electromax 9kW combi be an environmentally-friendly choice? If so, let's look at its performance figures.

By law, all boilers manufactured and supplied in the UK must have a minimum energy efficiency performance level of 92% (equivalent to a SEDBUK "A" grade). Until April 2018, the minimum performance level was 88% (88% and 89% are equivalent to a SEDBUK "B" grade and 90%+ an "A" grade).

Energy efficiency tests record how much energy is wasted on non-core functions during normal operation.

The energy efficiency rating of the Heatrae Sadia Electromax 9kW is 99.8% with a SEDBUK band rating of "D".

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

The ERP (Energy Related Products Directive) applies to all products that consume energy at any time in their lifetime, from manufacture to disposal and at all points in between.

The intention of this European legislation is to encourage manufacturers to offer end users products that are better for the environment through the creation of fewer harmful gas emissions at all points of a product's life cycle.

The Heatrae Sadia Electromax 9kW has an ERP rating of "D".

In reality, however, nearly every electric boiler on the market in Britain has an operating energy efficiency near 100%. Electric boiler ERP scores appear low because the electricity generation process currently involves burning fossil fuels, which is considered carbon-intensive, and this is factored into the score. Here at PlumbProud, we don't believe this is comparing like with like.

How many years does the warranty period cover on a Heatrae Sadia Electromax 9kW boiler?

The manufacturer offers a parts and labour warranty of 2 years on the Heatrae Sadia Electromax 9kW boiler to new customers.
