Is there a rain shower or double shower? Because of the high water flow, you need a double shower pipe heat recovery system. The large amount of hot shower water used is divided over two Shower Pipe WTW VX 2100 Twin HE heat exchangers. This shower heat exchanger can therefore extract maximum residual heat and ensure the greatest energy savings. Want to know more about our Shower Pipe WTW VX 2100 Twin HE? Read on quick.
Shower Pipe WTW VX 2100 Twin HE
The Shower Pipe WTW VX 2100 Twin HE is easy to install. You will receive a wall plate with two 2100 Twin HE HRVs on it . We also supply various couplings and Turbo rotators.
- 70.5% efficiency at 12.5l/min
- 72.6% efficiency at 9.2l/min
- Fast installation thanks to prefab solution
- Maximum flow of 22 litres per minute on the drinking water side over the WTW
- Less susceptible to damage and theft
- Even better contribution BENG
- No solder joints

INSTALLATION OF SHOWER PIPE-WTW
A shower pipe heat recovery :
- provide you with an EA back-flow protection (controllable check valve with integrated ball valve)
- place vertically
- can be installed in combination with a thermostatic shower mixer tap
- must remain accessible in its entirety
- you are not allowed to isolate
- you do not necessarily have to place it directly under the shower (small carry-over is possible)
- can only be connected to the shower drain
TURBO ROTATOR
Our shower pipe HRVs are supplied with a TURBO rotator as standard. This attachment ensures perfect entry of warm shower water and therefore high efficiency.
MAINTENANCE & CLEANING
- A shower pipe heat recovery system is maintenance-free and self-cleaning due to the high flow
- In case of additional cleaning, a natural soap-based cleaning agent is preferred

FAQs
Can I connect the bath to the shower heat recovery system?
It is not permitted to connect a bath to a shower pipe heat exchanger. This has to do with the diameter reductions in an appliance pipe, in this case a bathtub.
- The odor trap (I) for a bath has a diameter of ⌀ 4 0mm ;
- The reduced diameter of the wall and floor pipe ( III) is ⌀ 50mm for a bath ;
- The appliance pipe (II) for a bath must be ⌀ 75mm.
It is mandatory that the pipe diameter in the appliance pipe is always increased one step at a time. If you install a shower pipe heat exchanger, it must actually have a diameter of at least ⌀ 75mm, while the shower pipe has a diameter of ⌀ 50mm. So that is too small.
Can I insulate a shower heat recovery unit?
No because of the risks for legionella. Always follow the installation steps in the installation manual.
Do I need to clean a shower pipe heat recovery system?
This is not necessary. Due to the high flow of water, the shower pipe heat exchanger is self-cleaning. Do you still want to clean extra? This can be done by rinsing with soap-based cleaning agents, see the manual for this.
Can I hide the heat exchanger?
The shower pipe is considered a sanitary appliance. It must be accessible without demolition work and replaced if necessary. A screwed panel is usually used;
Should the pipe be placed vertically?
You must mount the tube vertically because of the cyclonic effect inside the tube. Mount the shower pipe heat recovery within <1° vertically. Use a spirit level for this.
Can you connect multiple showers to one shower pipe heat exchanger?
This depends on the maximum water flow. Inquire about the possibilities.
Can the shower pipe heat exchanger be placed in a meter cupboard?
Yes, provided the meter cupboard is compartmentalised during installation.
