Is the Heatrae Sadia Amptec U1101 a standard, combi or system boiler?

The Heatrae Sadia Amptec U1101 is worthy of consideration if you're looking for a electric Flow boiler for your flat or house.

In many properties, combi boilers are more suitable than traditional types of boiler. Combi boilers heat water instantly on demand, which they draw directly from the mains supply, removing the need for storage tanks that can take up valuable space in your home.

A combi boiler is often the right choice for a smaller property, particularly if your home doesn't have a useable loft. As water is heated and delivered immediately rather than being kept warm for hours in an immersion tank, combi boilers reduce electric usage, thereby minimising your heating costs.

The main disadvantage of combi boilers is that they can only heat a certain amount of water at any one time. This means that, if two people are using different taps or showers within your home at the same time, the flow of heated water to each will be reduced, as will the water pressure and temperature.

Is a Heatrae Sadia Amptec U1101 electric Flow boiler suitable for my house or flat?

You should make sure that the boiler you install in your property is the right "size". And size doesn't mean its physical dimensions, size means how much power it has - the "output".

Your boiler should be able to cope with peak hot water demand in your property and not just your average hot water usage. The output rate of a boiler is measured in kilowatts and tells you how much power a boiler can use to provide hot water to your taps, showers and radiators.

If the output of your boiler is too low, there will often be times when your water isn't as hot as you want. But if your boiler output is too high, it will be more costly to run (often unnecessarily).

The output of the Heatrae Sadia Amptec U1101 electric Flow boiler is 11 kW kilowatts. Which types of property would this be appropriate for?

A PlumbProud Gas Safe engineer would recommend that the most suitable type of property for a Heatrae Sadia Amptec U1101 electric Flow would be smaller homes and apartments containing up to 10 radiators and providing hot water for one bathroom.

What size is the Heatrae Sadia Amptec U1101 boiler?

The Heatrae Sadia Amptec U1101 stands at 1,050 mm tall, 90 mm wide and 90 mm deep.

Is the Heatrae Sadia Amptec U1101 a condensing or non-condensing boiler?

Electric boilers like the Heatrae Sadia Amptec U1101 don't need to be "condensing", unlike gas and oil boilers. That's because, unlike gas and oil boilers, electric boilers do not burn any fuel which creates still-warm exhaust gases that condensing boilers then use to, among other tasks, heat water coming back from your radiators. They are, by design, more efficient in operation than non-electric boilers and they're not covered by the 2005 law requiring all boilers to be "condensing".

How energy efficient is the Heatrae Sadia Amptec U1101 electric Flow boiler?

With environmental issues in the spotlight, more and more homeowners are becoming concerned about how they heat their homes and how much they're contributing towards combatting climate change.

The power we need for our central heating systems accounts for around 14% of the UK’s greenhouse gas production. There are often dangerous levels of ambient nitrogen dioxide gases in the atmospheres of British cities because of our use of gas boilers.

If you decide to install a Heatrae Sadia Amptec U1101 electric Flow in your home, will you be helping the environment with your choice? Let’s have a look at the figures.

By law, the minimum level of energy efficiency for all boilers manufactured in and supplied to the UK is 92%, equivalent to a good SEDBUK “A” rating. Prior to April 2018, the minimum was 88% - boilers whose energy efficiency levels were 88% or 89% were given a "B" rating on the SEDBUK scale and those at 90% or higher were given an "A".

The energy efficiency rating awarded to each boiler indicates the amount of energy that is wasted when in operation.

Following testing, the Heatrae Sadia Amptec U1101 was given an energy efficiency rating of 99.8% and a SEDBUK grading of "D".

The boiler is however penalised in its ERP rating for being powered by electricity.

The Energy Related Products Directive (ERP) is European legislation that applies to all products which use or consume energy during their lifespan, including during the manufacturing process and when they're in actual use, right through to the point of final disposal.

The aim is to encourage the manufacturers to create new products that are kinder to the environment and which create fewer harmful gas emissions.

The ERP rating for the Heatrae Sadia Amptec U1101 is "D".

Many electric boilers are usually rated fairly low in ERP tests and unfairly so. Operational energy efficiency for electric boilers is actually around the 98-99% level in most cases. The reason they're marked down so severely is that the electricity used to power these boilers is generated by burning fossil fuels, which is considered carbon-intensive, and this is factored into their scores - not exactly a like-for-like comparison, in our opinion.

Does a Heatrae Sadia Amptec U1101 electric Flow boiler come with a warranty period?

The Heatrae Sadia Amptec U1101 boiler is provided with a parts and labour warranty lasting 2 years.
