Instant

Instant water heaters pretty much do what they say on the tin, they provide heated water immediately. They have a compact design which minimises the space it requires and makes them great for using in remote areas. They are energy efficient as they have no standby energy losses and you do not need to have a stored cylinder.

Water Cylinders

Our cylinders make it faster for your bath to fill up or gives you a shower that packs a punch. They offer features such as inbuilt sensors, safety tools and visual menus. They are designed for ease of use in the home.

Electric Boilers

Our modern range makes less noise and offers many more features than older models.

Over Sink

Over sink water heaters provide hot water without the need to install a separate hot water unit. These can provide small amounts of hot water at a time which makes them perfect for small office kitchens, hand wash areas and outbuildings or caravans.

Vented Under Sink

Vented water heaters are a great choice for when the water heating needs to be localised. This product is often employed when the central boiler is far away or if there is not one at all. These can be used for both domestic and commercial installations and installations is simple and straightforward.

Unvented Under Sink

An Unvented water heater is a cost-effective solution for residential or commercial properties as its installation is so flexible. There is no need for a separate cold-water supply, and it produces hot water using the mains pressure and provides a balanced supply to all outlets.

Hand Wash Units

Our small water heaters for hand wash basins are economical as they keep water at a consistent temperature. They are splash-proof and have an Ip rating of IP24. They are also easy to fit and install than many of the stored water heaters. They give hot water on demand and are suitable to supply your water outlet economically with power.

Your guide to installing your product

All our self-install products come with a manual and diagram. Some of our larger products come with a kit which includes a step-by-step guide.

Should I use vented or unvented?

Both have advantages; unvented offers more pressure yet vented can continue to work even when the mains water has been turned off.

Choosing a cylinder size that is fit for purpose

Your choice depends on several factors. These include the size of the space available to you, the strength of the mains pressure and details of your existing heating system. We would recommend you measure your space and speak to one of our friendly operatives on 01473 276686.

Elnur electric boilers do not come with a flex as they are subject to different installation methods other than for example a radiator or panel, whereby the connection must be hard wired by a competent engineer.

The Elnur RFE electric radiators all have child locks on the settings panel to stop little hands from tinkering with your heating. The Elnur Connected range however, do not have a lock available on products in the range.
