Wood res are usually installed in the main living area, which is
the section of the home that is usually kept the warmest, being
the area in the home most frequently occupied. However,
before deciding on the best location for your Metro wood re
you may wish to consider:
• Water heating. If you are intending to have a wetback it
is important that the wood re is as close as practically
possible to the water storage cylinder.
• Split level homes are best heated when the wood re is
installed on the lower level, as the heated air will rise to the
higher levels.
• Building construction is another consideration. Specied
clearances from walls, curtains etc must be maintained
and you need to ensure no structural beams or internal
gutters etc are directly above your preferred site. If you
have a two storey dwelling you need to consider the
second storey to ensure you don’t have the ue directly
outside a second storey window.
Generally, you can install your Metro in your home anywhere
that suits you; Pioneer offer various fan systems to transfer heat
to other sections of the home that are not heated sufciently.
It is necessary if using a fan system that the Metro you have
purchased has sufcient output to heat the total area you wish
to heat. Your Metro retailer or installer will be able to advise if
you are uncertain.
If your home is in a classied “clean air zone”, and dependent
on requirements/restrictions which may be imposed by your
local territorial authority (council) you may or may not be able
to install a water heating device. If in doubt consult your local
Metro retailer.
Water heating is another key feature of your Metro wood re, and
on offer are a number of options depending on the model you
have purchased. Metro offer a 2kW wetback suitable for
the Tiny Rad and Tiny Ped. The ECO Wee Curve and Ambie One
cannot be tted with a wetback in a clean air zone, but they can
both be tted with a wetback if installed on a 2HA+ rural property.
All other ‘ECO’ Metro’s can be tted with the ECO wetback.
The Side wetback is suitable for the Wee Rad, Xtreme Rad,
Xtreme Rad Base & Xtreme Ped. Both R1 and R2 models cannot
be tted with a wetback at all.
Note: Wetbacks are not suitable for use in locations where the water
supply has lime content. Lime build up inside the coil will eventually
block the coil causing the wetback to fail.
Other considerations are:
• Distance from your Metro to the storage cylinder will affect
the amount of hot water produced.
• Your climate & the manner in which you will ‘re’ your Metro
will determine the amount of hot water produced.
Cost Savings
Wetbacks can enable substantial power savings, dependent
on the climate in the area in which you live. If you live in a cold
climate you are likely to use your Metro for many months of
the year, in which case a Pioneer wetback will reduce or even
eliminate your water heating costs over those months. If however
you live in a warmer climate and use your Metro for only a few
hours a day over the colder months, electricity savings will be
considerably less.
Water Pressure
A common misconception is that you must have a low-pressure
system to have a wetback; this is not true. You must have a
“vented” system and high-pressure cylinders are usually not
vented. However you can install an “indirect” cylinder which
contains a secondary coil inside the storage cylinder, enabling
you to have a wetback while retaining a high-pressure system.
