Smart solutions with minimal impact
Duct sealing, geoenergy, and Smart HWC systems are implemented without extensive rebuilding, saving time and minimizing disruption.
Energy solutions for air, heat and water
Tight ventilation ducts, efficient heating, and circulating hot water create a stable and well-functioning indoor environment year-round.
Save energy, cut costs
Energy-efficient solutions like duct sealing, geothermal energy, and Smart HWC significantly reduce heating demands and operating costs.
Profitable investment with lasting impact
Duct sealing, geoenergy, and Smart HWC deliver long-term benefits by lowering operating costs, enhancing performance, and increasing sustainability over time.

Tight ducts – improved climate and reduced costs
Duct sealing is a cost-effective method that enhances both ventilation and energy efficiency without the need for demolition. The technique involves applying a composite material inside the ventilation ducts, creating a new, sealed surface that reduces leakage and energy losses. This results in an improved indoor climate and less strain on the ventilation system—a smart solution for buildings with leaky ducts, especially those constructed before 1990. Sealed ducts also simplify compliance with legal requirements and make passing the mandatory ventilation inspection easier.
The method works in all types of buildings and can accommodate bends and transitions. It can reduce heating energy consumption by up to 70%, with the investment typically paying for itself within three to seven years.
Geoenergy – an efficient energy solution throughout the year
Wall to Wall Group also offers geoenergy solutions that harness solar energy stored in the bedrock to heat and cool buildings. A closed-loop system circulates fluid through deep boreholes, collecting heat in winter and coolness in summer. This provides a stable indoor climate year-round and is especially suitable for larger buildings.
Geothermal energy is often combined with district heating for optimal operating efficiency. This solution is both cost-effective and environmentally friendly, offering annual savings of up to 50% and a payback period of seven to nine years.


Smart HWC – Efficient hot water circulation without pipe replacement
Smart HWC is an innovative solution that improves hot water circulation without demolition or main pipe replacement. A specially designed PEX hose is installed within the existing system, creating individual circulation for each apartment. This results in faster hot water delivery, reduced water consumption, and more consistent temperatures.
In many buildings, the DHW system does not function optimally, leading to heat loss, waste, and an increased risk of legionella. Smart HWC minimizes these issues quickly and efficiently. It is installed without the need for wall demolition and is suitable for most buildings. When combined with relining, Smart Plumbing offers a cost-effective and less disruptive alternative to traditional main pipe replacement.
