Efficiency Information; Annual Efficiency; Heat To Water Efficiency; Standing Losses - REMEHA Gas 310 ECO Technical Information

The service side with the inspection cover on the heat
exchanger is considered to be the front of the boiler.
With a "left-hand" version, the flow, return and flue
connections are on the left of the boiler as you face
the front (service side). On a "right-hand" version, the
flow, return and flue connections are on the right of the
boiler as you face the front (service side). The boiler
instrument panel can be rotated to face the front or the
short side of the boiler (front will be standard unless
stated on the purchase order) (see fig. 04).
Important!!

When ordering a Remeha Gas
310 ECO, it is essential that the number of sections and
whether a "left-hand" or "right-hand" connection version
is required as well as the orientation of the instrument
panel (short or front side). The boiler comes entirely
assembled and tested and will include, as far as possi-
ble, all accessories ordered.

APPLICATION DATA

The Gas 310 ECO can be used on all new and refur-
bishment projects in both single and multiple configu-
rations. Conventional and room sealed flue system
capability means that the boiler can be sited almost any-
where within a building.
The Remeha rematic and "OpenTherm" weather com-
®
pensators (option) are able to communicate directly with

Note: NCV = Hi, GCV = Hs
the boiler/s controls to make full use of their fully modu-
lating features, ensuring that the boiler closely matches
the system demand at all times.
External control systems (BMS) can be interfaced with
the boiler to provide on/ off - high/ low or modulating (0
-10V) control options.
