EHC Astro 12kW Combi Electric boiler frequently asked questions

Which category of boiler does the EHC Astro 12kW fit into?

The EHC Astro 12kW is an option you may wish to consider if you’re looking for a combi boiler for your house or flat.

The UK has some of the smallest homes in the Western world, which is partly why combi boilers were introduced in the 1970s. Traditional boilers require one or more large storage tanks which they use to either heat water and keep it warm or store water intended for heating later. These tanks took up a lot of space in people's homes.

Combi boilers save space because they don't require these tanks to operate. Instead, combis draw water direct from your mains supply then instantly heat and distribute it on demand.

The biggest disadvantage in using combi boilers is that they have a maximum capacity volume for heating water. While this may not be an issue in a small household, it could be for a larger household where there is higher demand for hot water. When more than one person is using the water, it is distributed between the two points, reducing the pressure and temperature at each point.

Is a EHC Astro 12kW combi the right boiler for my house or flat?

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

This EHC Astro 12kW Combi boiler gets its power from electric and the power it's capable of producing is measured in kilowatts - the output rate is actually a kilowatt rate. The higher the output rate, the more kilowatts a boiler can use when heating water.

If you choose a boiler whose output rate is too low, it may not have enough power to make your water as hot as you would like. If you choose a boiler whose output rate is too high, you won't have to put up with lukewarm water but you will face higher electric bills.

The EHC Astro 12kW combi boiler has an output level of 12 kW, so which types of property would it be appropriate for?

To most experienced Gas Safe engineers, the EHC Astro 12kW combi Astro would be most suitable for smaller homes and apartments with up to 10 radiators and 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 EHC Astro 12kW Combi boiler's flow rate is 5 L/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.


EHC Astro 12kW size

The dimensions of the EHC Astro 12kW are 740 mm tall, 435 mm wide, and 320 mm deep.

Is the EHC Astro 12kW non-condensing or condensing?

Electric boilers like the EHC Astro 12kW 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 EHC Astro 12kW combi good for the environment?

How we heat our homes and the damage we might be doing to the environment as a result has become an important point of concern to many homeowners worried about climate change.

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.

Is the EHC Astro 12kW combi boiler an environmentally friendly choice for your home? Here’s what the figures say.

All boilers manufactured and supplied in the UK must achieve an energy efficiency rating of at least 92% (SEDBUK score of "A"). This is higher than the 88% that was the legal requirement prior to April 2018.

The energy efficiency rating is used to work out how much energy a boiler both uses and wastes when it's switched on and working normally - its standard functioning and operation.

The EHC Astro 12kW is rated as 100% energy efficient, equivalent to a "D" SEDBUK rating.

The ERP ratings of this EHC Astro 12kW 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 EHC Astro 12kW has an ERP rating of "TBC".

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 EHC Astro 12kW boiler?

A parts and labour warranty of 2 years is included when you purchase the EHC Astro 12kW boiler through PlumbProud.

EHC Astro 12kW Combi Electric boiler frequently asked questions

Is the EHC Astro 12kW boiler a standard, combi or system model?

If you’re looking for a combi boiler for your house or flat, you may wish to the consider the EHC Astro 12kW.

Traditionally, most boilers required you to find space in your property for one or more large storage tanks. These tanks would either keep water warm or hold it in reserve for later heating. Manufacturers originally introduced combi boilers to offer homeowners the same level of warmth and hot water without taking up as much space – remember that the UK has some of the smallest homes in the Western world.

With a combi boiler, the hot water needed for your radiators and taps is provided on demand. Water from the mains passes through your combi boiler and the technology within it instantly heats the cold water. It then distributes that hot water around your home.

The biggest drawback for combi boilers is that they have a maximum capacity in volume for heating water. This means that if someone wants to use the shower while another person wants to use a hot water tap, the amount of water reaching each point falls, resulting in a drop in water pressure.

Is the EHC Astro 12kW combi boiler suitable for my house or apartment?

Selecting the right boiler for your home means choosing a boiler that is the right size. And, by size, we don't mean how big it is, we mean how powerful it is - the "output".

Your boiler’s output is a measurement of the power it has available to it to heat the water you need for your radiators or for when you turn on a tap, bath or shower. A higher output rate means it has more power and can heat more water.

It's important to choose an output that matches the demand for water in your home because if your boiler has too low an output, you'll often find only lukewarm water comes out of your taps or heats your radiators. If it’s too high, you’ll be paying more for your electric than you need to.

The EHC Astro 12kW combi has an output of 12 kW, so which types of property would this EHC Astro 12kW Combi boiler be appropriate for?

An experienced Gas Safe engineer would be likely to recommend that this EHC Astro 12kW 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 all combi boilers, the "flow rate" (measured in litres per minute) is as important a consideration as output rate when choosing which model to go for. This EHC Astro 12kW Combi boiler's flow rate is 5 L/m.

Like all combi boilers, the EHC Astro 12kW draws water from the mains. It instantly heats that water and then distributes it to the parts of your home which need it - taps, radiators, bathrooms, and so on.

However, the water in the mains pipe that feeds your boilers has its own flow rate - normally between 10 and 12l/m. So if you choose a combi with a flow rate of 14l/m but local water pressure is equivalent to 11l/m, your boiler will actually operate at 11l/m - below its capacity.

In addition, if different family members want hot water at the same time (like for regular morning and evening showers) and your boiler has to provide hot water to your radiators at the same time, a combi boiler may not be suitable.

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.


Dimensions of the EHC Astro 12kW boiler

The EHC Astro 12kW measures 740 mm in height by 435 mm in width by 320 mm in depth.

Is the EHC Astro 12kW a condensing or non-condensing boiler?

Electric boilers like the EHC Astro 12kW don't need to be modified to be "condensing" boilers because they operate differently to gas and electric boilers. Condensing non-electric boilers recycle the exhaust gases created as part of their operation to, among other tasks, heat water coming back from radiators. Electric boilers do not create exhaust gases and are, by design, more efficient and economical to run.

How does the EHC Astro 12kW combi boiler rate environmentally?

How we heat our homes is an issue which many homeowners worry about as the world combats climate change and environmental damage.

Central heating accounts for 14% of greenhouse gas emissions in the UK. In larger British cities, gas boilers emit dangerous levels of nitrogen dioxide into the atmosphere.

Would installing a EHC Astro 12kW combi boiler in your home be a green choice? Let's look at the numbers.

Every boiler manufactured and supplied in the UK must have an energy efficiency rating of 92% (SEDBUK “A” rating). These minimums were made law in April 2018 - before that, the minimum energy efficiency rating was 88% (88%/89% = "B" SEDBUK grade, 90%+ = "A" SEDBUK grade).

The EHC Astro 12kW was awarded an efficiency rating of 100% and a band rating of "D".

Energy efficiency ratings for boilers describe the amount of energy they use and waste when switched on and working.

The boiler is however penalised in its ERP ratings for using electricity for power.

The ERP (or Energy Related Products Directive) is European legislation which applies to all products that consume energy throughout their lifetime.

Its purpose is to encourage manufacturers to offer products that are kinder to the environment by reducing harmful gas emissions at all stages, from production and end use right through to disposal.

Electricity generation currently involves burning fossil fuels, which is carbon-intensive. This is factored into the ERP scores of many electric boilers, although virtually every electric boiler has an energy efficiency in operation of near 100%.

The ERP rating for the EHC Astro 12kW is "TBC".

How many years' warranty does the EHC Astro 12kW combi come with?

The EHC Astro 12kW boiler comes with a parts and labour warranty of 2 years.
