Indirect Thermal Store with Alternative Heat Source Capability
The HeatStream Electric Plus range incorporates a primary heating coil, allowing connection to an alternative heat source such as a boiler or district heating system. The 14-bar rated primary coil provides excellent versatility and can pre-heat the store in as little as 10 minutes when connected to a suitable heat source.
This additional flexibility makes these thermal store cylinders an excellent option for a wide range of domestic applications.
Fast Hot Water Recovery
Large-surface-area stainless steel corrugated coils deliver rapid heat transfer, helping maintain a consistent supply of mains pressure hot water even during busy periods. The efficient design ensures hot water is available when it's needed, making it well suited to larger households with higher daily demand.
Combined with its generous capacity, this helps deliver excellent hot water performance throughout the property.
Efficient, Durable, and Low Maintenance
The HS210EPLUS-IOF achieves an ErP B energy efficiency rating with low standing heat losses of just 1.12kWh per day. It can also maximise the benefits of off-peak electricity tariffs and solar PV systems, helping to reduce running costs where appropriate.
The outer shell is manufactured from durable polyethylene for added protection against accidental damage, while the polypropylene inner tank is non-corrosive and particularly suitable for areas with poor water quality.
