OVUM passive domestic hot water heat pumps
OVUM domestic hot water heat pumps represent a revolution for hot water preparation in multi-party buildings. For the first time it is possible to ensure the high requirements of the drinking water hygiene standard B5019 simply and with minimum energy consumption. Each residential unit is individually equipped with the appropriate domestic hot water heat pump. Depending on the requirements a 100, 150 or 270 litre system can be installed. The 100 and 150 litre systems are designed as hanging storages.
Functionality of the passive domestic hot water
The OVUM hot water heat pumps use the heating backflow of the low-temperature heating system (underfloor heating) as a heat source. They take the required heat from the heating backflow and thus heat the domestic hot water in each decentralised unit up to 60°C. The heating system in the central unit supplies the required amount of energy for the domestic hot water preparation on a low-temperature basis in winter and in the transitional period. In summer the input of the passive energy by the underfloor heating is sufficient.
1 Domestic hot water heat pump
Efficient by using the underfloor heating of the apartment unit as a heat source at low temperature level. No circulation losses! No separate domestic hot water accounting!
2 Underfloor heating
In the summer months the underfloor heating of the each apartment is used as a heat source for the domestic hot water preparation.
3 Heat loss
In the distribution system, heat losses are reduced by up to 95% compared to decentralised appartment stations.
4 Heating centre
The central heating unit operates at a low temperature level and supplies the energy required for domestic hot water preparation additionally to the heating energy during the heating period.
NEW: now with PV control contact
Adjust the target temperature to the free electricity offered by your PV system.
The heating centre can be designed as a low-temperature system
Reduction of domestic hot water energy requirement by up to 75%
