Vaillant Turbomax Combi Boiler Review

The Turbomax was a range of non-condensing boilers from German company Vaillant. This range was in production from 2000 to 2010 and offered both system and combi boilers.  While it’s not possible to fit a new Turbomax boiler, you might move into a home where one is still in use. If you have one you may want to consider a new boiler installation.

It is worth mentioning that the old Turbomax boiler is no longer in production – You can get a fixed price in 20 seconds online here

Vaillant was initially established in Germany back in 1874. Since then, they have become well known for their high-quality products which are both reliable and energy efficient. Valliant was the combi boiler’s pioneer back in the 1970s and has continued to pioneer solutions for our heating and hot water needs.

It’s worth knowing that as a non-condensing boiler, the Turbomax has a much lower energy efficiency than condensing boilers. The non-condensing boilers lose a lot of the energy when producing heat, meaning that your money is quite literally disappearing up the Turbomax flue.  A condensing boiler will mean lower energy bills and a lower level of carbon being produced, making them a better choice for the environment too.

What Are Vaillant Turbomax Boilers?

As one of the last models of non-condensing boilers, the Turbomax was well known for its brass and copper components and its sturdy design. A combi boiler was available which provided hot water on demand removing the need for hot water cylinders and cold-water tanks and then a system boiler which requires a hot water storage cylinder.

If you find yourself with a Vaillant Turbomax boiler, the good news is that there is still good availability of spare parts. If you’ve mislaid your Vaillant Turbomax plus 828e user manual or those for any other model, then it’s easy to get an online version on the Vaillant website.


Vaillant Turbomax Boiler Features

Frost Protection

The Turbomax was equipped with a frost protection function. This caused the boiler circuit to heat to around  30°C when the temperature of the water drops to below five °C stopping any Vaillant boiler problems in winter.

Anti-cycling Control

When you’re using a boiler to heat the home, the temperature tends to fluctuate, which can mean that the boiler gets into a cycle of turning on and off. This economiser control prevents this from happening and results in the boiler running more efficiently. You will see the egg timer on your Vaillant boiler when this is happening.

Warm start Operation (Turbomax Plus Only)

The warm start functionality provided immediate delivery of hot water from the turboMAX plus boiler. When switched on, the warm start system enables the boiler to automatically light every now and then to maintain an internal temperature of the boiler at around 40 °C.
