Direct Pressurised Hot Water Cylinders for Efficient Domestic Hot Water Heating

Direct pressurised hot water cylinders are the most popular electric powered water heater or electric heating hot water system on the UK market.

Introduction to direct hot water cylinders

• Direct hot water cylinders heat water using electrical immersion heaters within the cylinder itself.
• Direct cylinders are fed directly from the mains pressure water supply. These cylinders offer high flow rates for showers,taps and baths without the need for a booster pump.
• Direct hot water cylinders provide a reliable and efficient way to supply domestic hot water to homes and commercial properties – utilizing mains pressure within the tank for improved flow rates in showers and baths.
• Unvented cylinders are designed to store hot water at mains pressure, making them suitable for any property location, for optimal performance.
• Direct unvented cylinders heat up water through an immersion heater within the hot water storage cylinder.
• Direct hot water cylinders are often constructed from highly corrosion-resistant materials like duplex stainless steel.

Quality manufacturing and proven technologies are essential in the production of direct unvented cylinders, ensuring a high level of performance and reliability.

Direct hot water cylinders are a perfect solution for properties with limited space, as they can be easily installed and maintained, reducing the need for additional plumbing.

Benefits of Direct Unvented Systems

Direct unvented systems offer numerous benefits, including high flow rates, efficient heating, and cost-effective operation, making them a popular choice for homes and businesses.

The use of energy cut out thermostats, temperature and pressure relief valve and control thermostats in direct unvented cylinders helps to reduce heat loss and minimize energy consumption, while also providing a high level of control and safety over the water heating system.

Unvented cylinders are available in a range of capacities, from 80 Litre to 5,000 Litre, making them suitable for properties of all sizes, and can be used to supply hot water to multiple showers and baths.

For our 80 to 500 Litre direct pressurised cylinder range which come with a 25-year warranty for domestic use (5 year warranty  for commercial use), please see the dedicated webpage –unvented direct cylinders

Direct unvented systems are designed to provide a reliable and consistent supply of hot water, making them ideal for locations with high demand, such as commercial properties, schools, hospitals etc. This webpage details our commercial electric water heaters

The benefits of direct unvented systems also extend to the environment, as they can help to reduce energy consumption and minimize waste, making them a more sustainable option.

Direct pressurised hot water cylinders are environmentally friendly due to the gradual phasing out of gas power sources.

Materials and Construction for Durability – Stainless steel

Stainless steel is a popular material for direct unvented cylinders due to its high level of corrosion resistance and durability, ensuring a long lifespan and minimal maintenance.

Quality manufacturing is essential in the production of direct unvented cylinders, ensuring that they are built to last and can withstand the demands of frequent use, while also providing a high level of performance and reliability.

The use of duplex stainless steel in cylinders, provides additional strength and resistance to corrosion, making them ideal for use in harsh environments.

Direct unvented cylinders are designed to be compact and space-efficient, making them perfect for properties with limited space, while also providing a high level of performance and reliability.

Insulation of the electric pressurised unvented cylinder

The construction of direct unvented cylinders is designed to minimize heat loss and optimize energy efficiency, making them a cost-effective option for homes and businesses.

Direct hot water cylinders should feature 40mm insulation to reduce heat loss. Our units have 60mm insulation for lower heat losses for our 80 to 500 Litre models.

Installation and Maintenance Considerations for direct unvented cylinders

Direct unvented cylinders require careful installation to ensure safe and efficient operation, and it’s essential to follow the manufacturer’s instructions and guidelines.

Regular maintenance is essential to extend the lifespan of the cylinder and prevent issues, such as corrosion and scale buildup, and it’s essential to check the direct pressurised cylinder regularly for signs of wear and tear.

The use of quality materials and construction in direct unvented cylinders helps to minimize the need for maintenance, while also providing a high level of performance and reliability.

The installation process includes components such as combination valves and immersion heaters.

Direct unvented cylinders are designed to be compact and space-efficient, making them easy to install and maintain, even in properties with limited space.

It’s also essential to consider the delivery and installation prices when choosing a direct unvented cylinder, as these can vary depending on the manufacturer and supplier.
