Mobile heating center and rental cooling – flexible helpers on construction or renovation

5 min


A mobile heater is coming during construction or renovation work more and more often to the train. No matter if you Dry water damage or simply a winter construction heating required, the possible applications of the mobile heaters are extremely diverse.

If temporary heat is required in winter, rental cooling is required for transitional supply in summer or when renovating cooling systems. The mobile heating and the cold water replacement can be connected to the existing infrastructure to bridge the gap. In the DIY sector, however, mobile heating is the variant that is used much more frequently.

1. Advantages and disadvantages: when to rent, when to buy?

The great advantage of mobile heating systems or a cold water replacement for rent is the fast and tailor-made availability. The operator’s obligations and proper operation are guaranteed by the landlord.

Tip: If the system fails during the rental period, the lessor will provide an equivalent replacement device. An important factor is always the regional proximity of the companies in order to be able to find a replacement quickly in case of doubt. Portals like Deutsche-Thermo.de offer comparisons of offers and help to find the right dimensioned system for the individual project nearby.

With regular use over several years, the same performance class or very small devices it may be better to buy the appropriate systems. The most important thing here is to be able to estimate exactly which device performance is required in the medium to long term.

However, especially in the event of interruptions in use, such as seasonal use, one should not forget that a device has been purchased after a long period of non-use may no longer work properly. If you are already outside the warranty, you usually pay for the repair or maintenance out of your own pocket.

rent mobile heating

Mobile heating centers or a cold water replacement are rented, especially when the periods of use are limited in time, such as a renovation or a new building.

2. Planning, implementation, delivery, construction: In 4 steps to the finished building heating

Regardless of whether you rent or buy, the planning process should always be similar:

2.1. Step 1: Define the area of ​​application

The operation with electricity is very unprofitable, especially with longer idle times.

In the first step, it is important to clearly define what you actually need the device for:

  1. What is the exact one Intended use?
  2. How large are the rooms to be heated or cooled?
  3. What temperatures should be achieved?
  4. is sufficient electricity available or does the device have to be delivered with an additional fuel supply?

Come as an alternative to electricity Heating oil, liquid gas or wood pellets in question. The following applies here: the higher the required output and the longer the operating time, the more expensive it is to maintain electricity.

If a 20 kW device runs for a week in 20 kW x 24 hours x 7 days full load to heat up the screed, you end up with 3,360 kWh consumption. At 0.30 € / kWh the electricity costs are around 1,000 euros. A comparable system with heating oil (currently approx. 70 cents per liter) would consume oil worth around 250 euros during this period.

2.2. Step 2: Find the right device

As soon as the framework conditions have been clarified, the selection of available options must be narrowed down. Here it is important to achieve the most precise balance possible between performance and consumption: If you dimension too small, you may not achieve the required performance. If you are unsure, portals or the operators of mobile heating systems can help. With precise information, the trained consultants can actually estimate relatively precisely how big the system must be.

Note: The following figures serve as a rough guide. For building heating, one calculates around 50-100 W / m³ in the shell, 25 to 30 W / m³ in a closed building, e.g. in a new building with windows and doors. Basically, the following applies: the better the property is insulated, the less energy is required. For a 30 m² room (with a 3 m ceiling height) in the shell, about 5 – 10 kW would be required. If the building already has windows and doors, the forecast consumption drops to 2-3 kW.

2.3. Step 3: get quotes

It is very important to compare different offers. Many providers may offer Additional services that are not absolutely necessary, others may offer “all-round carefree” packages for low surcharges. You should always get at least one comparison offer.

2.4. Step 4: delivery, installation and connection

Once the best provider has been found and the contract signed, all that remains is to deliver, set up and start up. In the case of smaller devices in particular, it can be worthwhile to pick them up yourself and to forego delivery. Larger systems should be installed by a specialist company, the prices are usually based on the amount of work.

3. Versatile, flexible in use: Mobile heaters are comparatively inexpensive

fitter checks checklist

Should there ever be a breakdown, a replacement or a fitter will be available in the shortest possible time.

The right mobile heating system is the greatest advantage when you rent mobile heating devices. The devices are available in different sizes, Depending on the provider, mobile heating centers as well as mobile refrigeration devices are ideally on the construction site within less than 24 hours.

Provided that it has been well planned in advance and the system has been precisely adapted to individual needs, the actual rental costs are manageable.

Depending on the size of the plant, alternative fuels should be considered, because the operation with electricity becomes very unprofitable, especially with longer idle times. In terms of the potential damage that improper heating can cause, mobile heaters and chillers for rent are comparatively cheap.

If it is a question of permanent operation or longer downtimes, a purchase may make more sense. However, it should be noted that you are responsible for the maintenance and repair of the device yourself. If there is a failure, you have to organize a replacement yourself.
