EHC Astro 12kW Combi Electric boiler frequently asked questions

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

The EHC Astro 12kW boiler could be suitable for your house or flat if you are looking for a new combi boiler.

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 a EHC Astro 12kW combi boiler right for my house or apartment?

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 EHC Astro 12kW Combi boiler be appropriate for given its output of 12 kW?

A PlumbProud heating engineer would recommend that this EHC Astro 12kW Combi boiler is 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.


How large is the EHC Astro 12kW?

The EHC Astro 12kW is 740 mm [H] by 435 mm [W] by 320 mm [D] in size.

EHC Astro 12kW – condensing or non-condensing?

In every gas and oil boiler, there is a flue that carries the exhaust gases created from the burning of the fuel required to power the boiler. As there is no fuel to be burned in an electric boiler, an electric boiler like the EHC Astro 12kW does not need to be adapted to be "condensing" as there are no gases to recycle. Electric boilers are naturally efficient and economic.

How energy efficient is the EHC Astro 12kW combi boiler?

How we heat our homes has become a pressing issue of concern for many homeowners worried about climate change and the environmental impact of their personal choices.

Approximately 14% of the UK's greenhouse gas production is caused by our central heating systems. The gas boilers in larger urban areas of Britain are mainly responsible for emissions of toxic nitrogen dioxide.

If you decide to install a EHC Astro 12kW combi in your home, will you be helping the environment with your choice? Let’s have a look at the figures.

In the UK, all boilers manufactured and supplied must have an energy efficiency rating of at least 92% or a SEDBUK "A" grade. Prior to April 2018, the minimum rating was 88% (88% and 89% are equivalent to a SEDBUK "B" rating and anything higher is rated as an "A" grade).

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

ERP assessors are however not keen that the boiler is powered by electricity.

The Energy Related Products Directive (ERP) was introduced in 2015 and applies to all products that consume energy throughout their lifetime, including during the manufacturing process and at the point of final disposal.

The purpose of the ERP is to ensure that companies create products that are kinder to the environment by reducing both the energy they use and the harmful emissions they produce.

An ERP rating of "TBC" has been awarded to the EHC Astro 12kW.

This is very low, but why? In reality, nearly every electric boiler on the market has an actual energy efficiency in operation of near 100%. However, some electric boilers have low ERP scores because the electricity generation process currently involves burning fossil fuels, which is considered carbon-intensive, and this is factored into the score - unfairly, in our opinion.

Is there a warranty on the EHC Astro 12kW combi boiler if it breaks down?

A parts and labour warranty of 2 years is included with the EHC EHC Astro 12kW boiler.

EHC Astro 12kW Combi Electric boiler frequently asked questions

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

The EHC Astro 12kW is worthy of consideration if you're looking for a combi boiler for your flat or house.

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 a suitable option for my house or flat?

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 EHC Astro 12kW combi's output level is 12 kW, so which types of property would this EHC Astro 12kW Combi boiler be an appropriate choice for?

Most experienced boiler engineers would recommend this EHC Astro 12kW Combi boiler as a suitable option for smaller homes and apartments with no more than up to 10 radiators and one bathroom.

You need to consider the flow rate as well as the output rate when choosing a combi boiler.

Flow rates, measured in litres per minute, indicate how much water your boiler can heat and distribute around your home at any given time. If your family regularly use hot water around the house at the same time and you have a lot of radiators, you should choose a boiler with a high flow rate. This EHC Astro 12kW Combi boiler's flow rate is 5 L/m.

However, you also need to consider the flow rate of your local mains water supply. Combis can only draw water from the mains as fast as the pipes can deliver it. If you choose a boiler with a 14l/m flow rate and the mains pipes into your home have a flow rate of 12l/m, your boiler won't be able to operate at full capacity. In other words, try to make sure the local water pressure and your boiler flow rates are as close as possible.

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 size is a EHC Astro 12kW boiler?

The EHC Astro 12kW boiler is 740 mm high, 435 mm wide, and 320 mm deep.

Is this EHC boiler condensing or non-condensing?

When a boiler is a "condensing" boiler, it uses the warmth present in the exhaust gases created by the burning of gas or oil to reheat cold water coming back from the radiators via a secondary heat exchange. Because electric boilers like the EHC Astro 12kW don't actually burn fuel in the home, they don't require a flue or a secondary heat exchanger - they're naturally more efficient by design.

Is the EHC Astro 12kW combi a good choice for the environment?

With so many of us worried about the environmental impact of our personal choices, the relationship between how we heat our homes and climate change has become an important issue for many 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.

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

In the UK, by law, all boilers manufactured for the UK market since April 2018 must have a SEDBUK “A” rating and operate to a minimum level of 92% energy efficiency. Prior to this, the minimum was 88% - 88/89% would score a "B" and 90% or more an "A" on the SEDBUK scale.

The energy efficiency rating measures the amount of energy a boiler consumes when it's in use and how much it loses on non-core operations.

Following testing, the EHC Astro 12kW was given an efficiency rating of 100% and a SEDBUK grading of "D".

The ERP ratings of this EHC Astro 12kW Combi boiler are however marked down because it is powered by electricity.

All products that consume energy throughout their lifespan must comply with the Energy Related Products (ERP) Directive.

Companies are legally obliged to reduce harmful gas emissions at all stages of a product's life cycle, from initial manufacturing right through to final disposal as well as when the product is in use.

As fossil fuels generate the power used by electric boilers, some receive low ERP scores because electricity generation is carbon-intensive. This is unfair because the actual operational energy efficiency of most electric boilers is either 98% or 99% - a level no oil or gas boiler has yet reached.

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

What warranty do I get if I purchase the EHC Astro 12kW boiler?

The EHC Astro 12kW is covered by a parts and labour warranty of 2 years following installation.
