Is the Heatrae Sadia Amptec C900 a combi, system or regular boiler?

Suitable for a house or a flat, the Heatrae Sadia Amptec C900 electric Flow boiler is worth considering if you want a electric Flow boiler.

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.

Would the Heatrae Sadia Amptec C900 electric Flow be a suitable choice of boiler for my house or flat?

Selecting the right boiler for your property means selecting 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".

The output of a boiler is measured in kilowatts. The output level determines the maximum power a boiler can use in heating the water needed for the baths, showers, taps and radiators in your home.

It's important to choose a boiler with an appropriate level of output for your property. Your boiler should be able to cope with periods of peak demand in your property and not just your average usage.

An output rate that is too low will result in an inadequate supply of hot water, while an output that is too high will mean the boiler will cost more to run than is necessary.

The output of the Heatrae Sadia Amptec C900 electric Flow is 9 kW kilowatts, so which types of property would this be appropriate for?

A heating engineer would recommend that the Heatrae Sadia Amptec C900 electric Flow boiler would be a suitable installation option for smaller homes and apartments with up to 10 radiators and one bathroom.

What size is the Heatrae Sadia Amptec C900 boiler?

The Heatrae Sadia Amptec C900 stands at 1,050 mm tall, 90 mm wide and 90 mm deep.

Is the Heatrae Sadia Amptec C900 condensing or non-condensing?

As a large proportion of the greenhouse gases released into the atmosphere come from people's homes, the Government passed a law in 2005 requiring all manufacturers to make gas and oil boilers "condensing". What this means is that they must include a secondary heat exchanger, which recycles the warmth contained in exhaust gases normally expelled via the flue so that they're more efficient. Because electric boilers like the Heatrae Sadia Amptec C900 don't actually burn any fuel, there are no exhaust gases to recycle and they are exempt from the requirement to include a secondary heat exchange.

Is the electric Flow Heatrae Sadia Amptec C900 boiler energy efficient?

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.

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.

Do the figures suggest that installing the Heatrae Sadia Amptec C900 electric Flow at your property would help in the fight against climate change?

All new British boilers must perform to a legal minimum energy efficiency of 92% (a low to good SEDBUK "A" rating). Prior to April 2018, the target was 88% (86-90% = SEDBUK "B" and 90%+ = SEDBUK "A").

Efficiency ratings are intended to let consumers know how much energy a boiler uses in its day-to-day activities and how much energy goes to waste.

The Heatrae Sadia Amptec C900 was awarded an efficiency rating of 99.8% equivalent to a SEDBUK grade of "D".

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 Heatrae Sadia Amptec C900 is "D".

What warranty do I get if I purchase the Heatrae Sadia Amptec C900 boiler?

The Heatrae Sadia Amptec C900 boiler has a warranty covering parts and labour costs for up to 2 years after installation.
