Hot water is one of the greatest uses of energy for the traveller. Gas hot water systems have several problems: Operate at around 40% efficiency and are relatively costly to run. Are vulnerable to dust ingress into burners rendering them unreliable. Are bulky & heavy when the weight of the gas bottle and mandatory tank is included. LPG is a highly flammable and dangerous energy source. Require venting as they consume oxygen and emit dangerous Carbon gasses. Electric Hot Water system have several advantages: Electric power can be generated by solar or alternator or both and are inexpensive to run. Are sealed units unaffected by dust Are lightweight and compact in either tankless or tank versions Are protected by circuit protection creating a perfectly safe syste. Do not require venting. Tankless Electric Hot Water These are commonly called “Instant Hotwater” and are compact and most efficient. However, to heat water passing through at “speed” requires a lot of power. So they require a high amount of power but use the least amount of energy as they are only “on” for a short period of time. To achieve 55C from cold 15C water requires 6,000-7,000W of power. As the water source gets colder, the power required rises. This is too much for even 6,000W Inverters so a different customised solution was needed for the RV market. Problem Solved This Instant Hot Water operates at a range of power settings. These settings are from: 2,500W to 6,000W. Once a setting is locked, the system retains it in memory and will restart after power off/on to your required setting.
