Heatrae Sadia Amptec C600 - a regular boiler, combi boiler or system boiler?

The Heatrae Sadia Amptec C600 is a electric electric Flow boiler.

In older British homes, traditional boilers required you to find room for one or more storage tanks. One tank would keep hot water warm and the other stored cold water for later heating. Manufacturers introduced combi boilers to the UK in the 1970s so that homeowners could get the warmth and hot water they needed without having to sacrifice too much valuable space – remember that residential property in this country is among the smallest in the Western world.

Combi boilers deliver hot water to your radiators and taps using water they draw directly from the mains supply. As mains water travels through a combi boiler, the technology within it heats the cold water instantly and on demand. The hot water is then distributed throughout your house.

Combi boilers have one drawback, however: they can only heat a certain amount of water within a given time. For example, if someone uses the shower and another person uses the hot water tap at the same time, water pressure drops because water reaches each point differently.

Would the Heatrae Sadia Amptec C600 electric Flow boiler be suitable for my house or flat?

Whether this Heatrae Sadia Amptec C600 Electric Flow boiler is right for your property depends on its size or what its "output" level is. Size does not mean its physical dimensions, however - it means how powerful it is.

The output rating indicates how much energy a boiler can use in providing you with hot water and heat when you need it from your radiators and taps. The greater the output, the more water it can heat.

It's better to take advice on this from a registered installer because, if your boiler output is too low, your water and radiators might not get as hot as you would like them to be. However, if the output level is too high, you'll end up paying more on your electric bills than you need to.

Which types of property would this Heatrae Sadia Amptec C600 Electric Flow boiler be appropriate for given its output of 6 kW?

A heating engineer would recommend that the Heatrae Sadia Amptec C600 electric Flow boiler would be a suitable installation option for smaller homes and apartments with up to 10 radiators and one bathroom.

What dimensions does a Heatrae Sadia Amptec C600 have?

The Heatrae Sadia Amptec C600 occupies a space of 1,050 mm high by 90 mm wide and 90 mm deep.

Heatrae Sadia Amptec C600 – condensing or non-condensing?

Electric boilers like the Heatrae Sadia Amptec C600 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.

What energy efficiency ratings have been awarded to the Heatrae Sadia Amptec C600 electric Flow?

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.

In Britain's bigger cities, gas boilers, in particular, are responsible for dangerous levels of nitrogen dioxide emissions. Overall, 14% of all of the UK’s greenhouse gas production comes from heating our homes.

Do the available figures suggest that installing the Heatrae Sadia Amptec C600 electric Flow in your property would be an environmentally friendly choice?

All boilers manufactured in the UK or supplied to UK domestic properties must achieve a legal minimum energy efficiency rating of 92% (equivalent to a good "A" grade using the SEDBUK scale). Prior to 2018, the minimum was 88% (88% and 89% are a "B" SEDBUK grade and anything 90% or above is an "A" grade).

The energy efficiency rating of a boiler refers to the amount of energy it uses to perform its everyday functions as well as the amount of energy it wastes.

The Heatrae Sadia Amptec C600 has been awarded 99.8% for its energy efficiency, equivalent to a SEDBUK "D" rating.

The boiler's poor ERP rating, however, reflects how it is marked down for running on electricity.

The Energy Related Products Directive (ERP) came into force in 2015. It was introduced to encourage manufacturers to create more energy-efficient products and covers all products that consume energy during their lifetimes, including energy used during production and at the point of disposal.

The Heatrae Sadia Amptec C600 has been awarded an ERP rating of "D".

In truth, however, the actual operational energy efficiency of most electric boilers is 98% or 99% - a level no oil or gas boiler has yet reached. So why does it receive such a low ERP score? It's because fossil fuels generate the power used by electric boilers and factoring this in results in low efficiency scores since electricity generation is carbon-intensive. We're not sure this is a fair way of comparing energy efficiency given the advances in electric boiler technology over the last 5 years.

What is the warranty period on a Heatrae Sadia Amptec C600 electric Flow boiler?

Heatrae Sadia’s Amptec C600 boiler includes a parts and labour warranty of 2 years.
