Stainless Lite HP - heat pump and solar unvented hot water cylinders

Gledhill Stainless Lite HP (Heat Pump and Solar)


Unvented hot water cylinder with heat pump and solar inputs

Heat Pump technology to create domestic hot water

 

 

Gledhill Stainless Lite HP unvented hot water cylinder for use with heat pumps

Stainless Lite HP standard models

Heat pump technogy could be the answer to renewable energy use. The new Gledhill unvented stainless steel unit, the 'Stainless Lite', specifically for heat pump applications is designed with renewable energies in mind. Utilising the well established Gledhill Stainless Lite unvented hot water cylinder, this product has been developed to maximise the lower temperatures typically available from heat pumps.

The heat exchanger is a totally new design. It consists of a two pass corrugated stainless steel tube in parallel to reduce the pressure loss whilst maximising the heat exchange. Many medium to large heat pumps need heat exchangers in the store that will cope with the higher flow rates associated with primary temperatures that are typically 50˚C or 60˚C.

All the usual features of the Gledhill Stainless Lite are maintained together with controls* and expansion devices included. (*with the exception of solar control and Heat pump contol that should be supplied with these add-on systems)
 

Due to the fact that many heat pumps may not raise the stored water temperature to 60˚C, which is necessary to prevent the growth of legionella, the Stainless Lite HP model is supplied with an immersion heater tapping and a thermostat pocket.
 

It is recommended that a thermostat is fitted which brings the immersion heater ‘on’ at a temperature just below the heat pump maximum (if required) and switches off at 60˚C or 65˚C. In this way the use of ‘direct’ electrical heating is minimised and most of the hot water is achieved from the heat pump and solar input as available.
 

Tappings
 

The Stainless Lite HP is supplied with all the necessary connections including two 10mm dry thermostat pockets.

Notes:

1 All connections are supplied with compression fittings for direct connection to copper pipework.

2 The suggested model sizes shown are based on a typical days hot water use assuming that the heat pump will heat the domestic hot water to approximately 50˚C.

3 When connecting to solar heating input, it is important to check the dedicated solar volume is suitable for the total floor area to comply with Building Regulations.

4 The Stainless Lite HP units are the same whether you are running solar thermal systems in conjunction with heat pump or just using a heat pump input only.

5 The solar dedicated volume is only applicable when used in conjunction with solar thermal systems.

6 When selecting a solar model, it is important to check the dedicated solar volume is suitable for either the total floor area of the dwelling or the total net area of the

solar panel to ensure compliance with Building Regulations.

7 Maximum solar panel area is calculated based on 25 l/m2 of net solar panel area.

8 Heat pump kW rating performed at 80˚C and 0.25 l/s.

 

* Only applicable when used in conjunction with solar thermal systems
** Where solar thermal system is not installed
*** For compliance with Building Regulations & SAP
**** For compliance with Building Regulations @ 25l/m2 of the collector area
