1.0 Introduction and Location
1.1 Introduction
The Atmos MonoSolar makes use of advanced technology to produce hot water. It
consists of a 100 litre insulated thermal storage tank, a heat exchanger, a multi speed
pump, an electronic control module and a solar panel.
Water from the storage tank is circulated around the solar panel, gaining heat from
the sun. A 22mm copper heat exchanger coil immersed in the tank transfers the heat
to the tap water, so that it can be used for low pressure or mains pressure
applications. The circulation through the panel is called “low flow”. This means that
the water flows slowly through the panel and therefore gets sufficient time to heat up.
The water that returns from the panel into the cylinder has therefore the highest
possible temperature. This water doesn’t mix with the colder water in the cylinder
because it gently drops back. Because of this principle, the top of the water in the
cylinder gets hot first, which means that hot water is available very quickly. This
saves energy and cost.
The MonoSolar has an in built control system which protects it against temperature
extremes. If there is a risk of overheating in the summer, or of freezing in the winter,
the circulation of water is automatically stopped, allowing water to flow back from the
solar panel into the empty discharge space in the storage tank.
This means the Atmos MonoSolar can operate without the addition of expensive
antifreeze. The storage tank and solar panel form a sealed circuit so that there is no
way oxygen can enter and form corrosion in the cylinder.

Like all solar heating systems, an electric circulation pump is needed to pump the
water round the system. This uses electrical energy, but the MonoSolar control
system cleverly uses a multi-speed pump. On start up it runs for two minutes at high
speed, and then the speed drops to low speed for the rest of the time. So whilst heat
is being collected, the pump uses only 23 watts of electricity. This is a hidden but
significant energy and cost saving feature.
A thermostatic mixing valve ensures that the water flowing from the tank can be
adjusted to meet user requirements, and avoid any possibility of scalding.
