Pulse-air workshop and hall heating

Tested and approved

approved for Austria, Germany, Italy and Switzerland




Puls-air is a compact, fuel oil operated workshop and hall heater. It is operated with the patented pulsating combustion, which comes from rocket research. Due to the extremely economical combustion, the heater pays for itself.

Thanks to approval as a mobile heater (no central heating) for workshops and halls, you benefit from the Puls-air advantages at present and in the future.



Simply take it with you when you move: the Pulsair hall heater only weighs approx. 75 kg
Space-saving: the Puls-air heater only requires approx. 1 square meter of floor space

Sustainable thanks to effective combustion & low CO2 emissions, 97 % efficiency

You can carry out service work yourself

Quality made in Austria - see for yourself!


The size and degree of insulation of the room determine which or how many devices are needed to heat it. All necessary information about the devices, such as heating power, KW, weight, size, etc. can be found on the product page. Mainly workshops and halls are heated with Puls-air. In a broader sense, the compact warm air heaters can also reliably and economically heat tents, construction sites, conservatories, etc..

Top device and a very smooth operation for years. We have now purchased our 2nd device from the company Pletzer and are very satisfied. By positioning 3 exhaust pipes and a flexible exhaust hose on the heater, we can now alternately move the device and heat each.

Everything top, 5 deserved stars. Here is a small addition. After the new purchase, there was a problem. The company sent me a replacement unit during this time. After the repair, we exchanged the devices again. All in all, I am very satisfied and can only recommend this equipment and the company.

From around € 140 per month
you finally get your heating costs under control!

You can either buy or lease your Puls-air workshop heater at a low price.
It has never been so easy to heat your workshop at a low price.*

*Without down payment, residual value 10% of purchase value (AW) plus VAT, term 48 months. Leasing offer via our partner MMV Leasing GmbH, subject to credit check, etc. There are no additional costs. The stated leasing rate is the net rate (plus 19% VAT for Germany & 20% VAT for Austria). MMV Leasing carries out a contract acceptance check before the contract is concluded. Warranty extensions and steering wheels increase the leasing rate. 


Basically you can say:

Puls-air standard with very good insulation 600 m³.

Puls-air Plus up to max 1800 m³ with good insulation, with poor insulation 1000-1200 m³.

Very well insulated are halls or workshops built up to 5 years ago. This means insulating glazing, gas concrete walls or sandwich panels 100 mm or 120 mm.

Poorly insulated halls, for example, are just masonry buildings with poor roof.

Room temperature as desired. Based on empirical values, the room temperature of the workshop can be reduced by approx. 4 degrees, while maintaining the same comfort level for the employees, because the heat comes from below. Compared to ceiling fans from above, therefore energy is senselessly wasted.

Yes, because a room thermostat is built into the unit, which automatically turns the unit off and on to maintain the set temperature.

The external fuel oil tank is to be obtained from the local heating contractor. Requirements: Double walled, leak detection & fire protection valve.

No, the unit can be connected to an external fuel oil tank via 8mm copper pipe. Attention: No return - single line system. The tank can be up to 30 m away and the height difference must be max. 3.5 m.

The advantage of the canister is that the device is immediately ready for use.

Approx. 57 dBa, measured in a reference room. The actual noise sensation in a normally equipped workshop or hall is a pleasant light hum.

Judging loudness is often difficult.
  • 30 dB: Whispering, own breathing sound.
  • 35 dB: Leaf rustling.
  • 40 dB: In the living room with the window closed.
  • 45 dB: Residential area without road traffic.
  • 60 dB: Entertainment (single conversation)
  • 70 dB: Open plan office.
  • 85 dB: Average road traffic.
  • 95 dB: Heavy traffic.

Puls-air Standard: 1.5 l/h at the economy level and 1.9 l/h at the full power level

Puls-air Plus: 1.9 l/h at the economy level and 2.5 l/h at the full power level

Attention: Do not calculate on the complete day, because the device always switches itself on and off by the thermostat to maintain the temperature.

We always ask the counter question: How much do you need at the moment? - From this minus 50% and then you have the sum (All in approximate figures)

Yes, but this must be connected by us according to the circuit diagram, because the fan must run after.

App control is possible. Your local electrician should contact us in this regard!

Basically there are 2 models: Puls-air Standard (up to 600m³) and Puls-air Plus (with good insulation up to 1,800m³). For even larger premises, 2 or more units can be operated together. Thus, even larger halls and workshops can be heated efficiently and economically.
