Minimum energy consumption for the single-family house

Renewable sources reduce the energy consumption of the single-family house to almost zero

Type of intervention: new construction with passive house standards

Climate zone: D, day degrees 1574

Tatano products: Kalorino fireplace, KS Medium model with wood/wood pellets; forced circulation solar heating system L500.

Customer needs:

The new home incorporates lines and construction materials characteristic of local architecture, but it is absolutely innovative from the point of view of energy consumption, so as to satisfy the passive house criteria.

The choices regarding the envelope and the technical systems were conditioned by the regulatory constraints on the energy performance of the new buildings. In view of the initial investment costs, the client requested a system of simple management, comfort at the highest levels and the possibility of remote control of the system.

Project solution

Thanks to the use of innovative solutions and products - Kalorino KS Medium wood/wood pellet fireplace integrated with a 500 L forced circulation solar thermal system, combined with a fan coil heating system - the energy requirement is entirely met by renewable sources and the costs associated with heating and domestic hot water production are minimal.

The exploitation of renewable energy sources also satisfies the customer’s request for sustainable and low environmental impact solutions.

Project details

The heart of the autonomous heating system is the KS Medium wood / wood pellet fireplace, which is combined with 4 forced circulation solar thermal panels installed on the roof. The solar system, managed by digital regulation, is connected to a 500 L thermal cell, with an integrated 100 L domestic hot water storage tank. Solar integration heats the domestic hot water first and, once reached the set point starts to accumulate the energy inside the inertial storage.

The production of heat and sanitary hot water is therefore entirely entrusted to renewable energies, with significant benefits in terms of reducing energy consumption and polluting emissions, always maintaining the highest levels of comfort.
