Heat pumps mean you can tap into the natural energy available in the ground and in the air. Hoval can offer you a clean, efficient and environmentally sensitive solution.

The use of heat pumps means that you no longer need to have a chimney on your house and they allow you to drastically reduce the emissions you produce. They make use of the tiny temperature differences in the soil, or water or in the atmosphere. Together with a small amount of conventional electrical energy they can produce heat for the whole house. A heat pump from Hoval gives a clean and efficient solution.

The earth on which we live remains at a constant temperature of 10° to 12 °C at a certain depth, even in deepest winter. At a depth of 100 m the temperature is about 13 to 15 °C and with increasing depth it continues to rise. This provides ideal circumstances for using an underground probe as a means of tapping heat energy.

The Hoval TopGas condensing boiler couples high efficiency with low emissions and satisfies demands for both economy and environmental protection. It features the Hoval UltraClean® combustion system with pre-mix down firing burner. This advanced burner is fundamental to the boiler achieving efficiencies of up to 109.7%.

Hoval condensing boilers are suitable for closed central heating and domestic hot water primary supply systems. The condensing operation also makes them suitable for under-floor heating installations requiring lower flow/return temperatures.

Low temperature boilers convert about 93% of the calorific value of gas into usable heat. With Hoval boilers, this limit is raised considerably by using unique condensing technology. The result is as much as a 15% increase in the amount of usable heat which dramatically increases the boiler efficiency. For even more comfort and flexibility the boiler can be provided with a remote controller.
