HybridHEAT is an energy-efficient heating system for both new buildings and renovated properties. Easy tender process, smooth planning, and quick installation are features that professionals value in hybrid heating.

One of the most critical decisions on a contractor’s table is the choice of heating system. Simplicity, reliability, and environmental friendliness should be combined in the same package and in a cost-effective manner, if possible.

Hybrid heating, which combines several different forms of heating, is an excellent solution for this need. HögforsGST’s Managing Director Antti Hartman has noted that the popularity of hybrid heating is starting to rise among renovation contractors and new buildings.

– Hybrid heating has been a popular solution in renovated properties for several years. Now it is also being implemented in a growing number of new buildings. From the contractor’s perspective, hybrid heating is an effortless and reliable choice. It combines environmental friendliness and reasonable investment costs, Hartman states.

Effortless process from bidding to installation

HybridHEAT is a modular, factory-tested system that can be efficiently designed to fit various purposes.

HybridHEAT makes the contractor’s life easier, as tendering and installation go smoothly, says Juha Virkki, Business Director responsible for HögforsGST’s Engineer Service.

– A hybrid heating system is easy to tender, as HybridHEAT’s quotation includes accurate return and investment calculations. The profitability of different heat source combinations can also be examined during the process.

– A wide field of designers and contractors can implement the design and installation of the modular HybridHEAT system. This makes the tender process easier, Virkki adds.

Budgeting is also more accurate thanks to the factory-made, modular components of HybridHEAT.

Delivery of the prefabricated parts to the site with clear installation instructions minimizes the time spent in on-site construction. The installers can primarily focus on connecting the factory-made components.

– And HögforsGST’s Engineer service offers comprehensive technical support during both planning and installation, Virkki adds.

In addition to the fast installation, a hybrid heating system’s advantages include the possibility of heating the property during construction.

If the hybrid system combines district heating and heat pump heat, district heating can heat the building in the construction phase.

Juha Virkki also points out that a hybrid heating system requires less space than e.g., a geothermal system of similar caliber. Smaller size makes planning and installing the system easier.

– A hybrid heating system requires significantly less space inside and outside the building. The number of heat pumps is smaller, and the geothermal wells need only a fraction of the space compared to a full geothermal system. The electrical infrastructure is also lighter when the electricity demand of the heat pumps is lower, says Virkki.

The lighter electrical infrastructure and smaller need for heat pumps and space also affect the cost of the hybrid heating system. The investment cost of a hybrid heating system is significantly lower than, for example, a geothermal system.

Another one of hybrid heating’s strengths is its flexibility: the property can use almost any energy source for heating.

A hybrid heating system can combine district heating, geothermal energy, exhaust air heat recovery, solar energy, heat pump energy, or any combination of these, to mention a few examples.

Juha Virkki says that the range of different hybrid systems is constantly growing across the Nordic countries.

Most of the hybrid heating systems we have implemented combine district heating and exhaust air heat recovery. However, the popularity of geothermal hybrid systems is also rising. For example, combinations of geothermal energy, district heating and/or heat recovery are examples of the versatility of the HybridHEAT, Virkki lists.

A property that chooses HybridHEAT also prepares for the changing energy market, as heat sources can be added into HybridHEAT’s “heat source palette” after installation.

– For instance, solar energy may be a more profitable energy source in the future than it is today. HybridHEAT is the only system that enables combining several different forms of renewable energy both now and in the future, Virkki says.

The real estate market pays increasing attention to the energy efficiency and environmental friendliness of the heating system.

In addition to the cost savings, the contractors can highlight the environmentally friendly hybrid heating in their marketing.

A hybrid system equipped with a heat pump can also be used for cooling if additional cooling-specific equipment is installed.

According to Antti Hartman, the need and demand for cooling is growing.

– Cooling is highly appreciated with the summers getting hotter, especially in new buildings. With a hybrid system, both heating and cooling is easy and cost-effective, says Hartman.

For the resident, a hybrid-heated apartment is a green choice. Also, thanks to the smart remote-control system, the hybrid system always operates efficiently.

Combining multiple heat sources also yields benefits by allowing the property to switch between heat sources as their market prices fluctuate.

Virkki uses a hybrid heating system with district heating and a heat pump as an example.

– When electricity is expensive, district heating can be prioritized in heating the property. When electricity is cheaper, heating can be produced with a heat pump. Thus, HybridHEAT can always produce heat with the cheapest heat source, Virkki calculates.

HybridHEAT systems are always delivered with the Fiksu Control System. Fiksu is a smart control system that optimizes the system’s operation and allows for remote monitoring and control.

Through real-time reports, residents can stay up to date with their energy consumption and the savings produced by the system.
