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

The Heatrae Sadia Amptec U1101 is an option you may wish to consider if you’re looking for a electric Flow 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.

Would the Heatrae Sadia Amptec U1101 electric Flow be a suitable choice of boiler for my house or flat?

You should make sure that the boiler you install in your property 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 has to be powerful enough to heat all the hot water you need for your radiators and taps. Power is measured in kilowatts and the more kilowatts a boiler has available to it, the more water it can heat.

If the output (measured in kilowatts) is too high, you'll have all the power you need and more but your electric bills will be much higher. If it's too low, you'll often find that the water coming out of your taps and fed into your radiators is only lukewarm.

With the Heatrae Sadia Amptec U1101 electric Flow's output at 11 kW, which types of property would this Heatrae Sadia Amptec U1101 Electric Flow boiler be most appropriate for?

A Gas Safe engineer would recommend that the Heatrae Sadia Amptec U1101 electric Flow boiler is a suitable choice for smaller homes and apartments with up to 10 radiators and one bathroom.

What dimensions does a Heatrae Sadia Amptec U1101 have?

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

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

Electric boilers like the Heatrae Sadia Amptec U1101 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.

Is the electric Flow Heatrae Sadia Amptec U1101 boiler energy efficient?

How we heat our homes has become a major issue for many people worried about climate change and environmental issues in general.

Central heating systems are responsible for 14% of greenhouse gas emissions in the UK. You may also be aware that the gas boilers we use emit dangerous nitrogen dioxide in large volumes in the bigger British cities.

Do the available figures suggest that installing the Heatrae Sadia Amptec U1101 electric Flow in your property would be an environmentally friendly choice?

An energy efficiency rating of 92% or above is a legal requirement for all boilers manufactured and installed in the UK today. 92% is equivalent to a low-to-middle "A" grade on the "Seasonal Efficiency of Domestic Boilers" (SEDBUK) scale.

Energy efficiency measures how much energy a boiler uses and wastes in the course of its normal operation. The lower the waste, the lower your electric bills.

The Heatrae Sadia Amptec U1101 was awarded an efficiency rating of "99.8%", equivalent to a "D" rating on the SEDBUK system.

The boiler's poor ERP rating however reflects the fact that it runs on electricity.

In 2015, the EU introduced the Energy Related Products Directive (ERP), the aim of which was to ensure that all manufacturers, including boiler manufacturers, developed more efficient products and processes.

The legislation aims to conserve energy at all life cycle stages, from initial production to the product's actual use by the customer, through to the point of disposal.

This Heatrae Sadia Amptec U1101 Electric Flow boiler's ERP rating is "D".

How is this so given that electric boilers are nearly always more efficient than their gas and oil counterparts, with an actual operational efficiency rating around the 98% to 99% mark, in most cases? Some electric boilers receive very low ERP scores because the electricity they draw for power is often generated by burning fossil fuels. In our opinion, this is unfair on electric boilers.

What warranty does the Heatrae Sadia Amptec U1101 electric Flow boiler come with?

The Heatrae Sadia Amptec U1101 boiler is covered by a parts and labour warranty of 2 years.
