Excelsior Water Heating

Since 1985, we have been water heater manufacturers.

We are pioneers in the water heating industry being the first company to manufacture stainless steel unvented water heaters in the U.K. and also the original innovators of the floating baffle which is now superseded by our innovative patented technology.

Direct, indirect, solar, heat pump, slimline, and horizontal water heaters are among our standard range of domestic & commercial products. Our highly experienced in-house design team would be delighted to talk to you about your own bespoke design.

We also offer a full range of water heater spares for our own and other OEM products.

How our water heaters work

Venturi Technology

Water drawn from the mains flows through a patented special inlet device using fluid dynamics to create negative pressure known as the ‘Venturi effect’. With precision design this configuration draws enough air to recharge the air gap as the tank is filled and requires minimal ongoing maintenance.

Features & Benefits

  • Enhanced Venturi Technology automatically replenish internal air gap
  • No expansion vessel or moving parts ensuring low maintenance
  • Evolved design for improved performance at low flow rates
  • 3 bar water pressure at the outlet (subject to incoming pressure)
  • Full range up to 500 litres, including heat pump and solar options
