Water Heaters

Instantaneous electric units heat water only on demand for single outlets such as hand-wash basins, while stored multipoint models supply several taps from one compact cylinder. Water heaters in this range include under-sink, over-sink and inline variants, often paired with matching Expansion Vessels / Kits and Pressure Reducing Valves to maintain safe operating pressures. Hyco and Triton models dominate the electric options, with Altecnic Caleffi supplying the supporting valves and kits.
