The Kwikot superline 400 dual is a high pressure electric water heater
The inner cylinder is manufactured from 1.6mm steel and thermofused porcelain enamelled for cylinder longevity and hygiene
The polyurethane insulation between the inner cylinder and the outer galvanised casement is 128% thicker, resulting in the hourly standing heat loss decreasing from 108 watts per hour to 50 watts per hour
