Electric Water Heaters at Lightshopdirect
At Light Shop Direct, we supply a wide range of electric water heaters and unvented water heating systems designed for both domestic and commercial use. Our selection includes compact, energy-efficient, and reliable unvented and inline electric water heaters that deliver hot water on demand. These units connect directly to your mains water supply, providing consistent pressure, fast heat recovery, and space-saving convenience, ideal for modern homes, offices, and commercial properties.
What Is an Unvented Water Heater and How Does It Work?
An unvented electric water heater is a closed system that heats water directly from the mains. Instead of relying on a separate cold-water tank, it uses a highly insulated cylinder to maintain water temperature efficiently. This design ensures a steady supply of high-pressure hot water, reduces heat loss, and delivers consistent performance throughout your property.
What Is an Inline (Tankless) Electric Water Heater?
Inline or tankless electric water heaters heat water instantly as it flows through the unit. Installed close to the point of use, these compact and energy-saving water heaters are perfect for kitchens, bathrooms, and utility rooms where space is limited. Their instant-heat technology eliminates the need for stored water, making them both eco-friendly and cost-effective.

Why Choose Light Shop Direct for Electric Water Heaters?
Upgrade your home or workplace with a high-efficiency electric water heater from Light Shop Direct — the smart choice for reliable hot water, energy savings, and lasting quality.
A vented water heater relies on a separate cold-water storage tank, while an unvented water heater connects directly to the mains supply. Unvented systems offer higher water pressure, improved efficiency, and a compact design ideal for modern homes and commercial applications.
Yes, both types are highly energy-efficient. Unvented water heaters feature superior insulation and advanced heating elements to minimise heat loss, while inline (or tankless) electric water heaters heat water only on demand — reducing energy waste and lowering running costs compared to traditional storage systems.
The ideal size depends on your usage. For smaller households or offices, a 10–15 litre unvented water heater is usually sufficient. For larger homes, kitchens, or commercial premises, consider units with 30–50 litres or more to ensure a consistent hot water supply.
Yes, both unvented and inline water heaters should always be installed by a qualified installer. This ensures compliance with UK safety regulations, proper pressure management, and optimal performance of your electric water heating system.
Inline or instant water heaters are typically designed for single-point use such as a sink or shower. However, some high-powered models can serve multiple outlets at a reduced flow rate. Our experts can help you choose the right model for your application.
Absolutely. Unvented water heaters are perfect for commercial use thanks to their reliable performance, strong mains pressure, and ability to deliver consistent hot water for washrooms, kitchens, and offices.
DeXpro unvented and inline water heaters come with a 2-year manufacturer’s warranty, providing reliable performance, energy efficiency, and long-lasting peace of mind for both residential and commercial installations.
