Introduction
Congratulations on your purchase of a Megaflo Eco SolaReady unvented water heater. The Megaflo Eco SolaReady is
manufactured in the UK from top quality materials and meets all the latest relevant safety and constructional standards.
The high grade Duplex stainless steel cylinder offers exceptional strength and corrosion resistance which is backed by a
Lifetime guarantee* Its performance and insulation levels exceed the latest requirements of Building Regulation Part L.
The Megaflo Eco SolaReady unvented water heater can be fed directly from the cold water mains supply to the property
without the need for separate feed cisterns or vent pipes. It is supplied complete with all its necessary inlet and safety
controls, electric immersion heater(s) and, for indirect units, a cylinder thermostat, thermal cut-out, 2-port motorised valve
and wiring centre.
Generally its pressure and flowrate performance will far exceed that from a comparable vented system, thermal store,
multipoint instantaneous gas heater, or combination boiler.
Please read and understand this product guide before starting work.

General Requirements
Important: Please read and understand this product guide before installing the Megaflo Eco SolaReady water heater. Incorrect
installation may invalidate the guarantee. This appliance is not intended for use by persons (including children) with reduced
physical, sensory or mental capabilities, or lack of knowledge and experience, unless they have been given supervision or
instruction concerning the use of the appliance by a person responsible for their safety. The Megaflo Eco SolaReady must
be Installed, Commissioned and Maintained by a competent installer in accordance with Building Regulation G3 (England
and Wales), Technical Standard P3 (Scotland) or Building Regulation P5 (Northern Ireland) and the Water Fitting Regulations
(England and Wales) or Water Byelaws (Scotland). Following Installation and Commissioning, the operation of the heater
should be explained to the user and the user guide left with them for future reference.
Storage
The Megaflo Eco SolaReady is supplied on a pallet with its associated control kits. It should be stored upright in a clean, dy,
frost-free environment prior to installation.
Siting the Megaflo Eco SolaReady (See Figure 1)
The Megaflo Eco SolaReady unit must be vertically floor mounted. It can be placed anywhere convenient provided the
discharge pipe(s) from its safety valves can be correctly installed. Areas that are subject to freezing must be avoided. Ensure
that the floor is of sufficient strength to support the “full” weight of the unit (refer to Tables 2 and 3 on page 7 for unit
weights). Pipe runs should be kept as short as possible for maximum economy. Access to associated controls, immersion
heaters and indirect controls should be possible for servicing and maintenance of the system.
Please do not install valves or pipework (except discharge pipe) within 50mm (2”) of the T&P relief valve to allow your
insulation set to be fitted. The insulation set is important to ensure heat and energy conservation. See page 12 for more
information.
To aid installation, the Megaflo Eco SolaReady is provided with lifting points located in the base moulding and two lifting aids
mounted on the upper rear casing. The weights of the units are noted on the tables on page 7, see tables 2 and 3.
