Renewable Hot Water Systems
Renewable
Overview

Renewable hotwater systems are a combination of multiple heat sources to create a robustly reliable and renewable solution to produce commercial quantities of hot water.  Air to water heat pumps have limitations in producing hot water, combining them with a 3 phase electric or gas backup creates an extremely reliable hot water system with the lowest possible running costs.  Heat pumps provide energy at a 4:1 COP reducing total amp draw and running costs, 3 phase electric or gas backup’s provide weather independent performance and high temperature boosting functions.  A fully electric or gas and electric system can be selected depending on the clients needs and available energy sources.

Renewable
Pure VED Electric Instantaneous

Vaillant’s new Pure VED fulfills a promise of optimal use of available energy. Whether as a replacement unit or for newly built homes or apartments – Vaillant’s electric instantaneous water heaters give you all the options for decentralised hot water supply in the bathroom and kitchen.

The Pure VED, with its attractive design and proven prize-winning technology, delivers a compact and space-saving solution which can be set to either 40ºc or 55ºc delivery temperature.
Whether for a single or multi-level family house, the Pure VED exclusively fulfills the highest hot water demands even when tapped to multiple points. The Pure VED is controlled electronically and delivers hot water at a rate of 8,10 or 12 litres per minute.

Renewable
Hybrid Mini

System Description

Dual aroTHERM air to water heat pumps backed up by an eloBLOCK 3 phase indirect boiler, recovers the hot water cylinders via the Habanero HX recovery system. The control system allows the heat pumps to add the greatest proportion of energy, only using the 3 phase boiler when required. The indirect nature of the heat pumps and boiler extends the plants life, especially in hard water environments.

Major Components

  • aroTHERM 16kW air to water heat pump
  • eloBlock 28kW 3 phase
  • aroTHERM buffer tank
  • aroTHERM hydrobox controller
  • VRC 700 cascade controller
  • Protank commercial series
  • Protank Habanero recovery system
  • Caleffi safety & temperature control valves

Renewable
Hybrid Maxi

System Description

Cascade of aroTHERM air to water heat pumps backed up by a pair of eloBLOCK 3 phase indirect boilers, recovers the hot water cylinders via the Habanero HX recovery system. The control system allows the heat pumps to add the greatest proportion of energy, only using the 3 phase boiler when required. The indirect nature of the heat pumps and boiler extends the plants life, especially in hard water environments.

Major Components

  • aroTHERM 16kW air to water heat pump
  • eloBLOCK 28kW 3 phase
  • aroTHERM hydrobox controller
  • VRC 700 cascade controller
  • Protank commercial series
  • Protank Habanero recovery system
  • Vaillant buffer tank
  • Caleffi safety & temperature control valves

Renewable
3 Phase Electric

System Description

eloBLOCK 3 phase indirect boilers, recovers the hot water cylinders via the Habanero HX recovery system. This allows a scalable solution where multiple boilers can be added in a cascade. The indirect nature of the boilers extends the plants life, especially in hard water environments.

Major Components

  • eloBLOCK 28kW 3 phase
  • VRC 700 cascade controller
  • Protank commercial series
  • Protank Habanero recovery system
  • Caleffi safety & temperature control valves

Renewable
Net Zero

System Description

An aroTHERM air to water heat pump is connected to a 40L buffer which recovers the hot water cylinders via the habanero HX recovery system.

The heat pump is supported by a 5kW PV system which is designed to 100% offset the power required to drive the system annually. The control system allows the heat pumps to boost the water temperature in the tanks when the PV system is producing power and coast when the system is using grid energy.

Twin electric elements in the buffer provide back up to the system. The indirect nature of the heat pump and heat exchanger extends the plants life, especially in hard water environments.

Major Components

  • aroTHERM 16kW air to water heat pump
  • Fronius Inverter
  • aroTHERM buffer tank
  • aroTHERM hydrobox controller
  • VRC 700 cascade controller
  • Protank commercial series
  • Protank Habanero recovery system
  • Caleffi safety & temperature control valves
  • Solar Panels
