Domestic Hot Water Air to Water Heat Pump

Ecocent is available in sizes up to 500ltr and is designed to fit in most airing cupboards it is a perfect cost effective replacement for a traditional pressurized hot water tank, whether retrofitting or new build.

A full product specification can be found below.

Ecocent controls are clear and simple to operate.

The cold air produced as a by-product of delivering hot water can be used for cooling applications such as supplementing air conditioning!

The cost of the Ecocent is comparable to a more traditional pressurized hot water tank system, but running cost is a fraction of the traditional system. Thus, the "payback period" is very short and cost savings are delivered throughout the life cycle of the unit and the savings run in to many thousands of €€€€€...

The unit has no harmful emissions.

 Stylishly designed domestic units can also be widely used in commercial buildings.

Ecocent is relatively light, making transportation to and around the installation site much easier. This , in turn, makes installation easier.

This unit provides:

  • A Mains Pressure hot water cylinder for your home that can produce over 1000 litres. a day with energy savings of up to 75%.
  • It always saves you money (even without sun) and no panels on your roof.
  • Very competitive pricing and easy installation.

Please note that the Ecocent is also capable of delivering space heating for small houses or apartments.  This can be done by using the secondary coil within the unit to deliver heat to a heating system.  This extremely versatile unit will deliver savings of up to 70% when used for suitable space heating applications.  ESP recommends that for space heating applications the Ecocent be used in conjunction with Smith's Ecovector radiators.

It does this as follows:

  • Air is drawn in to the top of the unit, heat energy is extracted (even cold air has energy) and transferred to the water.
  • Optional flexible ducts can lead to your roof space or any large indoor area, like a double garage, to maximize the use of latent heat sources.
  • Cooler, dehumidified air is expelled and can be used to cool areas such as kitchens, bakeries etc. (or pushed outside or back in to the roof space).
  • The process guarantees very low running costs.
  • The unit can run during the daytime to take advantage of warmer air and has programmable functions and timers.

NOTE:

  • The Unit is for indoor installation only (e.g. airing cupboard).
  • It is installed in the same way, and just as easily, as a conventional mains pressure hot water cylinder, with additional ducts to your roof space or elsewhere (as appropriate).
  • There is a 5 year warranty.
  • It has up to a 15 year life expectancy with virtually no annual maintenance required.
  • The Unit will produce substantial savings for the average family, making our heat pump a worthwhile investment with short payback time.
