Slimline Water Heaters for Restricted Spaces
EXCELSIOR WT slimline water heaters are designed for hot water systems where a standard cylinder diameter is not suitable. Their narrower vessel design makes them a practical choice for cupboards, tight service areas and restricted plant room spaces where installation width is limited.
The range includes slimline and super-slimline models, with direct and indirect options available depending on the heat source. Direct models use immersion heaters to heat the stored water, while indirect models connect to an external heat source through an internal coil.

Why Choose EXCELSIOR WT Slimline Water Heaters?
EXCELSIOR WT water heaters are built for installations where available space can limit cylinder choice. The slimline and super-slimline vessel designs allow reliable hot water storage to be specified where a standard diameter cylinder may be too wide.
The range gives installers a choice of direct and indirect models to suit different system requirements. This supports both electric heating and systems connected to an external heat source.
With stainless steel construction, external expansion and capacities from 80 to 210 litres, EXCELSIOR WT provides a practical water heating solution for restricted spaces without compromising on long-term durability.
