ECB 210 operation
the wiring centres
The Advance Electric Combination boiler is perfect for modern all electric apartment
dwellers who prefer the comfort of wet central heating systems and mains pressure hot
water for powerful showers and quick bath filling.
Two programmers are fitted and wired, one for off peak (usually overnight) electricity tariffs and
one for switching the central heating on and off during the day. The central heating programmer/
room thermostat is wireless and can be used without the need for additional wiring.

There is sufficient hot water from an overnight charge for a shower and a bath.
A second immersion heater is fitted for hot water boost.
The product meets HWA Thermal Store Specification and part G and L of the Building Regulations.
The lower part of the store is dedicated to central heating. A 6kw immersion heater is
fitted for this purpose, and can be used in systems up to four or five radiators. During
start up periods the energy stored in the lower part of boiler is ready for immediate
use. If the water in the radiators falls overnight to 20 °C, for example, the 6kw heater is
adequate for demand of up to 10kw when first switched on in the day.
When heating is switched on water is pumped from the store to the radiators and has the
benefit of providing immediate heat. Using the off-peak controller, the immersion heater
will have heated the store to 75 °C which is the recommended temperature.
A temperature gauge is fitted for convenience and diagnostics.
In the higher part of the tank is a large efficient hot water coil which draws heat from
the store for hot outlets in the property. It is connected to the mains so provides fast
safe hot water to all outlets without the need for pumps.
Your morning shower will not be compromised if the heating is on.
