Electric Hot Water
Electric Hot Water vs LPG?
- Zero operating cost if using solar
- Takes less space
- Efficiency is a little better in mobile applications
- Lower installed cost
There are three types of electric hot water
Prices are similar so it's just a matter of choosing what suits best
12V or 48V DC Tank Type
240V AC Tank Type
Tank-less or Instant Hot Water
12V or 48V DC tank electric?
- No Inverter needed
- Can be operated in parallel to inverter running
Added Benefit of 48V DC tank electric?
- Fast replenishment rate at 1,000W (5 x faster than 12V) and makes a smaller tank more feasible to use.
- Operating in a kitchen does not impact electric cooking on an inverter based power system.
- The temperature setpoint goes to 70C. if plumbed exclusively in the kitchen a tempering valve may not be required.
- It can be operated from solar/scotty while driving very efficiently.
240V AC tank electric?
- 10L and 15L are common sizes.
- Metal tanks suitable for off-road (rather than just a home system)
- 1500W so fast replenishment
Tankless electric hot water vs tank electric?
- Smaller in size
- Not carrying around deadweight of tank water as these models wont operate unless they are full.
- Disadvantage is the 240v electric power required.
Can you operate a Hot Water System without a 240V Inverter?
Yes, there are 12V and 48V tank based hot water systems in the 8L to 12L range.
The benefit of the Safiery 48V tank based hot water is:
the 1,000W of heating gives faster replenishment and makes a smaller tank more feasible to use.
Operating in a kitchen does not impact electric cooking on an inverter based power system.
The temperature setpoint goes to 70C. if plumbed exclusively in the kitchen a tempering valve may not be required.
It can be operated from solar/scotty while driving very efficiently.
Can we operate an instant hot water system for both the bathroom and kitchen?
This is not recommended. The main reason is the electric cooking appliances need to be off when using the instant hot water and this is not practical. Consider the 8L 48V tank hot water in the kitchen area.
What temperature of hot water is possible with instant?
In our tests that you can see on videos, we comfortably reached 40-45C from an 18C starting temperature. This is around 5000W. The flow rate is 3L/min
Customers have reported higher temperatures at lower flow rates of 2 L/min.
We have a customer posted video who get 40C+ on a 3000W inverter with a very low flow rate of 1.5L/min. The system needs at least 1.2L/min to operate.
