The Atmos Ephesus 24 system versions
The Atmos Ephesus comes in 4 main variations all of which include the Atmos Ephesus E24-Basic which comprises of:
- 150 litre hot water tank
- Unvented (mains pressure) kit
- Ground mounting frame
- Solar rated thermostatic blending valve
- 24 litre expansion vessel
- Frost protection thermostat
- 1.5kW 240V immersion heater and stat
- Anti-legionella timer (* varies with version – see below)
The basic system does not include any connection kit to a seperate hot water system, and is designed to heat water where you don’t have access to the boiler which makes it perfect for locations like campsites.
The E24-Unvented, E24-Combi and E24-CombiPlus all start with the E24-Basic system and include a connection kit to your heating system. There is also an alternate anti-legionella kit which pumps hot water from the heating system instead of using the internal immersion heater. This works much quicker than the electric heater, and uses low cost and low carbon energy.
Which version do I need?
If you have an unvented hot water tank (mains pressure hot water system) you’ll want the E24-Unvented system.
If you have a combi boiler which is solar compatible you’ll need the E24-Combi which includes a diverter valve. When the solar hot water is above 45 deg C it bypasses the boiler and goes direct to the taps. Below 45 degrees it goes to the combi boiler which tops it up to the boiler set temperature.
If your combi boiler is NOT solar compatible, you need the E24-CombiPlus which includes a special double acting valve. When the solar hot water is above 45 deg C it bypasses the boiler and goes direct to the taps. Below 45 degrees it goes to the combi boiler at 28 degrees, which then tops it up to the boiler set temperature.
How do I know if my boiler is solar compatible? When you send your enquiry to us take care to state the make and model number of your combi boiler, and if possible the date of manufacture. We will then check it for you.
The E24-CombiPlus includes a special valve, which incorporates a diverter and two thermostatic blending valves. It diverts the solar hot water direct to the taps above 45 deg, but below that it mixes it down to 28 deg so that the boiler can cope.
It’s not always obvious if a boiler is solar compatible so please complete our enquiry form with your boiler make and model and we can let you know which version you need.
