Description
The Megaflo Eco Direct 170L Unvented Hot Water Cylinder (95050466) is designed to provide reliable stored hot water for suitable 2–3 bedroom homes. With a 170-litre nominal capacity, two 3kW titanium immersion heaters and high-performance insulation, it offers a practical solution for properties that require dependable hot water without a separate cold water storage tank or shower pump.
Built with 60mm of CFC-free polyurethane foam insulation, the Megaflo Eco Direct 170L helps reduce standing heat loss, with a stated heat loss of 1.20kWh per 24 hours. Its internal floating baffle manages expansion within the cylinder, removing the need for a separate external expansion vessel in the specified configuration.
The cylinder comes with a factory-fitted temperature and pressure relief valve, 3 bar pressure reducing valve, tundish and unvented installation kit. With a stated maximum flow rate of up to 76 litres per minute at 3 bar, an ErP C rating and a lifetime guarantee for domestic installations, the Megaflo Eco Direct 170L is a robust option for compatible domestic hot water systems.
Megaflo Eco Direct 170L at a Glance
About the Megaflo Eco Direct 170L Cylinder
The Megaflo Eco Direct 170L is an unvented direct hot water cylinder. Unlike an indirect cylinder, which uses a boiler or another heat source through a heat exchanger coil, a direct cylinder heats stored water using its immersion heaters. This makes it suitable for installations where electric immersion heating is the intended hot water source.
Its two 3kW titanium immersion elements provide a combined rated electrical heating capacity of 6kW when both operate together. The stated heat-up time with both elements operating is approximately 93 minutes; actual performance can vary with incoming water temperature, electrical supply and operating conditions.
The cylinder's 60mm insulation helps limit heat loss, while the internal floating baffle accommodates expansion within the specified design. Factory-fitted safety components and the supplied unvented kit support installation, but the system must be installed, commissioned and maintained in accordance with the manufacturer's instructions and applicable regulations.
Key Features of the Megaflo Eco Direct 170L
1. 170-Litre Hot Water Capacity
Provides 170 litres of nominal stored hot water capacity, making it a potential option for suitable 2–3 bedroom properties. Actual suitability depends on household occupancy and hot water demand.
2. Dual Titanium Immersion Heaters
Includes two 3kW titanium immersion elements rated at 240V. Both elements provide a combined rated output of 6kW when operated together, subject to the correct electrical installation.
3. 60mm Thermal Insulation
CFC-free polyurethane foam insulation helps retain stored water temperature. The stated standing heat loss is 1.20kWh over 24 hours.
4. Internal Expansion Design
The internal floating baffle accommodates water expansion within the cylinder's design, avoiding the need for a separate external expansion vessel in the specified configuration.
5. Factory-Fitted Safety Components
Supplied with a temperature and pressure relief valve, 3 bar pressure reducing valve, tundish and full unvented kit to support the specified installation arrangement.
6. High Flow and Domestic Guarantee
The supplied specifications state a maximum flow rate of up to 76 litres per minute at 3 bar and a lifetime guarantee for domestic installations, subject to the manufacturer's terms and conditions.
Unvented hot water cylinders operate under mains pressure and require appropriate safety controls, discharge pipework and commissioning.

Frequently Asked Questions
1. How much hot water does the Megaflo Eco Direct 170L hold?
The cylinder has a nominal capacity of 170 litres. Whether this is sufficient depends on household occupancy, bathing habits and simultaneous hot water demand.
2. Is the Megaflo Eco Direct 170L suitable for a home with 2–3 bedrooms?
It is described as suitable for many 2–3 bedroom homes, but the correct cylinder size should be chosen based on the number of occupants, hot water usage and expected peak demand.
3. What is the difference between a direct and an indirect cylinder?
A direct cylinder heats its stored water using immersion heaters. An indirect cylinder normally uses a separate heat source, such as a boiler, through a heat exchanger coil. Choose the type that suits your property's heating system.
4. Does this cylinder need an external expansion vessel?
The supplied specifications describe an internal floating baffle that manages expansion, so a separate external expansion vessel is not required in the specified configuration. Always follow the manufacturer's installation instructions.
5. How many immersion heaters does it have?
It includes two 3kW titanium immersion heaters rated at 240V. The supplied heat-up time is approximately 93 minutes when both elements operate together; actual performance can vary with operating conditions.
6. Does the Megaflo Eco Direct 170L require a pump or header tank?
The unvented design is intended to operate from a suitable mains water supply and does not require a conventional cold water header tank or a separate shower pump. Actual flow and pressure depend on the incoming mains supply and installation design.
7. What is the guarantee on the Megaflo Eco Direct 170L?
The supplied information states a lifetime guarantee for domestic installations. Check the current manufacturer terms, registration requirements and exclusions before purchase.
8. Who should install an unvented hot water cylinder?
Installation and commissioning should be carried out by a suitably qualified professional with the appropriate competence for unvented hot water systems, following the manufacturer's instructions and applicable UK requirements.
