A NEW HOUSE WITH AN AIR-TO-WATER HEAT PUMP
Heating with an ESTIA air-to-water heat pump is one of the most environmentally-sound and cheapest heating options available. There is a great deal of freedom right from when you start planning to heat your new home with a heat pump. You don't need to include space to store fuel and all the pipework needed to heat your hot water can be taken into account when planning the building. The ESTIA All in One allows domestic hot water to be heated and prepared in one unit and is highly suited to all modern heating circuits with low supply water temperatures.
Underfloor/panel heating
Supply water temperatures are between 25°C and 40°C. The ideal temperature depends on the structural circumstances such as flooring, insulation, etc., and the personal preferences of the inhabitants.
Radiators
Depending on the age and design, supply water temperatures of between 35° and 60°C are needed here. This also depends on general conditions such as room size, number of radiators, insulation, personal comfort levels, etc.
Fan coil units
In terms of how they work, these are similar to an air conditioning system. They can be used to heat and cool a room, and can be operated with a wide range of supply water temperatures and are therefore well suited to a large number of applications.

WHAT DOES AN AIR-TO-WATER HEAT PUMP CONSIST OF?
All ESTIA air-to-water heat pumps are what are known as split systems, i.e., the refrigeration cycle is split over two units: an indoor unit and an outdoor unit. The outdoor unit is used to generate and convert energy while the indoor unit transfers it to the heating circuit.
The outdoor unit
Dimensions and volume depend on the heating and cooling capacity. The unit is quick and easy to install taking account of local circumstances.
The indoor unit
The Hydrobox is ideal for a new heating system. With dimensions of 72.5 x 45 x 23.5 cm (HxWxD), the Hydrobox can also be installed in small rooms. Weighing just 27 kg, it is easy to mount on the wall and leaves plenty of free space for more storage.
Control
All ESTIA systems have an integrated control panel. By adding a WiFi module, you can control your air source heat pump from any location using the TOSHIBA AC control app. By fitting an additional wired remote control in the home, it can also be controlled locally, from say the living room.
COMBINING A HEAT PUMP WITH PHOTOVOLTAICS
You will need a supply of electricity in order to run an air source heat pump. To do this as efficiently and environmentally friendly as possible, the ESTIA can be easily combined with a PV system. This makes your heating system even cheaper to run.
