Powerstream Ascari
Central Heating and Hot Water Flow Boiler
This electric boiler is 99% efficient and provides a versatile and safe way of heating water wherever there’s mains
electricity. Suitable for unvented wet central heating and domestic hot water systems, the Powerstream Ascari
electric boiler can be used as a direct replacement for Gas, Oil, Propane, Solid Fuel or Electric Storage heating*.
The Powerstream Ascari boiler also provides maximum flexibility as it does not require costly servicing, safety
checks or a flue.
Application

The Powerstream Ascari boiler has been designed to provide the highest temperature stability and energy
consumption possible from an electric boiler. Its 5 litre storage and high thermal mass reduce system
cooling, while its electronic temperature and auto-adaptability function keep the room at a stable temperature
using the least amount of electrical energy.
Complementing an alternative energy system
The optional outside temperature sensor allows the boiler to quickly adapt to the external temperatures,
increasing heat output on cooler days and reducing energy on warmer days, keeping temperature and energy
completely under control.

Running Costs
The Powerstream Ascari boiler is fitted with an auto-adaptability function that operates the central heating
system according to the heat characteristics of the property, minimising energy consumption and running
costs. The Ascari is designed for use with extended hours off-peak tariffs. Please ask your energy supplier
for details of optimum tariffs.

Input
Filling Loop
The Powerstream Ascari is not fitted with a filling loop. Any filling loop being fitted should comply with the
water supply (water fittings) regulations 1999 Section G24.1 and G24.2. A filling loop should be fitted at some
point to allow the CH system to be filled.
Parallel
Operation
For larger properties, multiple boilers may be installed in parallel.

Boiler sizing: Please consult your installer/heating engineer/designer as to the correct size of the Powerstream
Professional boiler. Size of the property, the insulation properties of the building itself, the local and seasonal weather
conditions and exactly what the boiler will be required to heat, eg: heating and/or hot water will need to be considered. To

Hot Water
Storage
Ask for the Redring Aqualoy LWSS 2304 Duplex Stainless Steel water storage heaters that provide
effective, fast and safe hot water for baths, showers and other domestic appliances around any property.
For use with direct and indirect heating applications the Aqualoy LWSS cylinders are a high quality vessel
employing the best in tig welding technology, the LWSS range also features high flow rates and energy
efficient insulation.
NB 1: The Redring Powerstream Professional flow boiler is ideal for providing water to a domestic /light commercial wet central heating
system. Where it is intended for use to provide hot water as well, it may be that an alternative direct source of heat is required, eg:
immersion heater. This is to ensure compliance with NHBC guidelines and to provide hot water at all times.
NB 2: The Redring Powerstream Professional flow boiler requires fitment of a circulating pump for underfloor and central heating
applications. In the case of unvented applications an expansion kit will be required.
