Vaillant ecoTEC Plus 832 Combi Boiler – Review, Prices & Alternatives

Since the end of 2015, combi boiler manufacturers have been working in line with the ErP guidelines set by the EU; to make boilers more efficient. This is one of the reasons the Vaillant ecoTEC Plus 832 combi was released–and why we’re reviewing it today.

The ecoTEC Plus range from Vaillant incorporates a few different models, suitable for a range of properties.

  • ecoTEC plus 825
  • ecoTEC plus 832
  • ecoTEC plus 835
  • ecoTEC plus 838

Before we go any further, take a peek at our new boiler cost guide. In summary, we rate Vaillant as a top-tier brand, similar in quality and price to Worcester Bosch and Baxi.

Worcester Bosch tend to be the best value for money for one simple reason; they have great a relationship with online boiler installation company, Heatable. Being supplied Worcester boilers so cheap, the overall installation cost is extremely competitive.

What Happened to the ecoTEC 831?

One of the biggest sellers for Vaillant was the 831. Instead of upgrading the 831, Vaillant chose to replace this model altogether; it’s now been discontinued.

The 832 is the new replacement which is not just more energy efficient, but offers various advantages including increased output for hot water, as well as the flow rate being slightly higher.

ecoTEC 832 Output

The improvements are marginal, but every little helps. The 831 and 832 both share a 24kw hot water output. However, the domestic hot water output increases from 31kw to 32kw. It’s a tiny difference, but if you regularly fill a bath, it’s noticeable.

Other improvements include an increased flow rate of 0.3 litres per minute, from 12.7 up to the new 13 litres per minute.

Suitable Property Size

Due to the increase flow, hot water output and heating output, the Vaillant ecoTEC 832 is suitable for properties that have a high demand for heating and hot water. This means it won’t have any trouble supplying an averaged sized 3-4 bedroomed property. This assumes 1-2 bathrooms.

Properties larger than this, or those with exceptionally high hot water demand (2 showers running at once) are going to need something a little more powerful. In the Vaillant range, the options are limited to the 835 or 838.

Vaillant 832 Features

Most boilers nowadays are A-rated, just like the Vaillant 832. This means that owners will enjoy and efficiency rate of 89.4% which makes this ErP compliant.

An important feature is the Quiet Mark compliancy. Appliances are tested to be within a certain noise tolerance and the Vaillant 832 passes with flying colours. Particularly useful if a family member works odd hours and a normal boiler is likely to wake you up.

ecoTEC Plus 832 Warranty

Like all premium boilers, the ecoTEC Plus 832 comes with a long 7-year warranty. You’ll be able to get a similar boiler (Worcester Bosch), at a similar price, but with a 10-year warranty using this clickable form on Heatable’s website.

Vaillant 832 Price & Alternatives

The Vaillant 832 is currently priced approximately £1,200 (boiler only – prices will fluctuate). That does make it slightly expensive.

We’ve covered the best combi boilers here.

The Logic Plus 30 has a slightly lower hot water and heating output and flow rate; almost unnoticeable. All Ideal Logic Plus boilers come with a 7-year warranty and the 30C is priced at £800.

If you’d prefer an increased hot water, heating and flow rate over the 832, the Logic Plus 35 offers all three. Again, a 7-year warranty and priced at just under £1,000; a £200 saving on the 832.

The Logic Plus range is a compact boiler. So, they will fit a standard sized kitchen cupboard; great if your home is open plan.

Worcester also offer a couple of alternatives. Compared with the 832 ecoTEC Plus and Logic 30+, the Worcester 30I is a good option (will not fit in a kitchen cupboard), priced at around £1,050. This is more than the Logic Plus 35 (which includes much more in terms of power).
