Home > Horsebox > Horsebox Water and Blown Air Heating >   Propex Heatsource 2000 LPG Blown Air Heating   Heatsource blown air heaters conform to the latest European standards for both the appliance and the electronics and during the rigorous testing the focus is very much on safety. The heaters also have to comply with an enhanced version of the Electro Mechanical Compatibility Directive to ensure they do not interfere with other electronics and that they are immune from interference by other electronics. The intelligent electronics are continuously monitoring the operation of the heater to make sure everything is operating correctly and safely. This includes monitoring of the flame, case temperature, combustion airflow, gas solenoid valve and voltage. Should any of these stray outside of the predetermined levels, the heater will be switched off and the red light on the thermostat will indicate a fault by flashing a certain number of times. Installation Both the HS2000 and HS2800 are supplied with complete fitting kits to suit either vehicle or marine applications. In vehicles and caravans the unit is usually mounted in a bed-box or cupboard, flued downwards through the floor and out to the side of the vehicle using flexable stainless ducting. These ducts (22mm i.d. for the HS2000 and 26mm i.d. for the HS2800) are supplied as standard in lengths of 750mm for vehicles and 1 metre for boats. The ends are finished with neat stainless steel end-caps which comply with EN624. The heat is ducted to one or more outlets through tough highly flexible 60mm or 76mm ducting. In the case of multi-outlet installations, the first outlet is an open outlet with directional control and the rest are closable and are used in conjunction with the appropriate sized plastic Y-branches. Marine applications feature an attractive polished stainless steel through hull fitting which accepts the stainless steel pipes for the flue outlet and the combustion air inlet. Extra ducting and stainless steel bulkhead mounting brackets are also part of the marine fitting kits. Economy The chart below reflects the consumption of gas if the heater was running continuously. In reality, both heaters have similar very high efficiency ratings, so the overall gas consumption will be about the same because the HS2800 will be running for a shorter period of time before the thermostat switches it off   HS2000 HS2800 Average consumption 142 grams/hour 225 grams/hour 3.9kg propane cylinder 27.5 hours 17.5 hours 4.5kg butane 31.7 hours 20.0 hours 13kg propane 91.5 hours 58.0 hours 15kg butane 105.6 hours 67.0 hours 19kg butane 133.8 hours 84.5 hours 47kg butane 331.0 hours 209.0 hours 904 Camping gaz (1.81kg) 12.75 hours 8.0 hours 907 Camping gaz (2.72kg) 19.0 hours 12.0 hours Our Price: £439.99 « Back
