Webasto Heaters | We are a webasto Heaters main dealer with full facilities. NARROW, BARGE AND HOUSE BOATS WATER HEATERS Water heaters can easily work at maximum capacity. Important factors to be taken into consideration when deciding on your heater are radiator sizes and their output wattage. E.g A single 2'6" x 18" radiator is about 600w. With a narrow boat and four radiators this
size - 600w x 4 rads = 2400 watts. Calorifier tank is approx. 1kw = total of 3400
watts. Therefore a 4kw heater would be
sufficient. | Model | Vessel Size | | THERMOTOP E - 4KW (up to four or five rads) | Narrowboats up to approx 40' | | THERMOTOP C - 5kw (up to six or seven rads) | Narrowboats up to approx 40' Wideboats up to 50' | | THERMO 90S - 9kw (up to ten rads) | Narrowboats from 60 - 70' Wideboats up to 70' Barges up to 85' Houseboats with up to 5/6 rooms | Air heaters are generally not suitable for canal boats and barges due to the length of ducting required. Radiator capacities and wattages can be obtained from plumbers merchants catalogues | | |
