1.0 INTRODUCTION
The Alpha FlowSmart system is a domestic hot water system designed to provide a
high level of heating and hot water performance more efficiently. The combination
boiler provides high volume and flow of instantaneous hot water using a patented pre-
heat system and central heating via a sealed heating system.
2.0 SYSTEM OPERATION
The Alpha FlowSmart system has been designed to deliver domestic hot water at a
high level of performance more efficiently, for example up to 18 l/min for temperatures
of 50°Candabovefor longperiodsofdemandusinglessenergythanatypical hotwater
storage system utilizing a large cylinder.
The cold water supply first passes through the GasSaver where the reclaimed heat
from the hot flue gasses is used to pre-heat the cold water supply. This pre-heated
water then enters the coil in the primary store where it is heated to a higher
temperature.
This hot water is then blended into the inlet of the combination boiler at a temperature
of approximately 30°C to give a constant pre-heated supply to the boiler. The boiler
then further heats the water to the required outlet temperature. When the flow of hot
water is stopped, the FlowSmart store is reheated and then the system is ready to
provide the same performance again.
3.0 IMPORTANT INFORMATION
The Alpha FlowSmart must be installed as described in these instructions. The Alpha
boiler must be installed in accordance with the instructions supplied with it. Failure to
do so will negate the warranty supplied with this unit.
The FlowSmart system has been approved to the relevant requirements of the building
regulations for primary hot water storage systems and the UK Water Regulations. It is
the law that all gas appliances are installed by a competent person, i.e. Gas Safe
registered engineer, in accordance with Current Gas Safety (Installation and use)
Regulations and all current Building Regulations.
Failure to install any part of the FlowSmart system correctly could lead to prosecution.
It is in your own interest and that of safety to ensure that the law is compliedwith.
Manufacturer’s instructions must not be taken in any way as over-riding statutory
obligations.
It is essential that the central heating system is thoroughly cleaned and flushed before
fitting an Alpha FlowSmart system. Failure to do so will invalidate the warranty.
If it is not possible to clean the system before fitting the new boiler, the system should
be cleaned using a proprietary cleaner and a magnetic filter connected in the return
before the boiler as this is the most effective method of ensuring that any magnetite and
rust particles are prevented from entering and damaging the boiler. Once the system
condition has been restored, an effective magnetic filter and strainer should be fitted
permanently to the system as a method of collecting any magnetite and rust from the
system during operation.
