What would you like to know about GAS WATER HEATER 20KW?



Gas heater with large heating capacity for e.g. hot tubs and spas

Discount! If you're planning to buy the gas heater HGJSD1219 and HGUNION19, it will be cheaper to buy the package HGJSD12C where HGUNION19 is included.

The gas heater has a large output for fast and safe heating. The capacity is 10 l/min and 25 °C temperature rise between incoming and outgoing water. This gives an increase of approx. 15 °C/h for 1000 liters of water. ATTENTION! As an accessory for connection to the hot tub, there is a set (HGUNION19) with pump incl. hose, transformer 230/24 V, input and output connections which can be ordered separately.

  • Nominal power 20 kW.
  • Gas consumption 1.5kg/h.
  • The heating time for a 1200 liter tub (6 - 37 ° C) is 2.5 hours, gas consumption 4 kg.
  • CE certified.
  • The fuel used is LPG (propane) with 30 mbar operating pressure.
  • Can be used for water heating in eg hot tubs, spas, hot water for showers, dish washing, etc.

The heater has automatic ignition, this requires a water flow of at least 7l/min to be activated. The pump in the HGUNION19 kit is specially made for this. If the water flow stops, the gas is shut off automatically. The same happens if the outgoing water for any reason becomes warmer than 75°C or if the flame goes out. The heater has a digital temperature display for incoming water.

A practical protective box is available as accessory for the gas heater that protect it from wind and rain. The front part on the box is detachable during use. The box has a fire proof material behind the heater  and sides. Above the heater there's a tilted fire proof part moving the heat outwards.
