Investment costs
The investment costs are based on the costs of a boiler
system. This includes the costs of the boiler, boiler
circuit control unit, pressure-jet burner and flue system,
as well as the costs of the safety equipment and return
flow temperature safeguard. The costs of the UNIMAT
UT-L boiler with condensing heat exchanger also include
the neutralisation of the condensate. Costs for
installation have not been taken into account.
Reflux of capital
In this example, the investment costs have been repaid
due to the lower fuel costs after about one year. It is
generally true that condensing technology pays for itself
faster the greater the output and the higher the fuel
costs. No subsidies have been taken into account in the
calculations. With the UNIMAT UT-L boilers, it is possible
to integrate further condensing heat exchangers. This
results in higher efficiency and therefore lower fuel
costs.

UNIMAT UT-L boiler
3.1.1
Equipment overview
The UNIMAT UT-L boilers are oil/gas special boilers for
positive pressure combustion to EN 303. These boilers
are designed to produce low pressure hot water with no
more than 110 °C (shutdown temperature of the high
limit safety cut-out) for heating systems that correspond
to the demands of DIN-EN 12828. The permissible
overall pressure must not exceed the permissible
pressure stage of the boiler. The modular design of the
boiler and additional equipment enables universal
application.
• Round boiler casing made of textured aluminium
sheeting
• Visible parts of the boiler primed in anthracite grey
and red
• Thermal insulation (100 mm) and extremely well
insulated burner door
• Boiler pressure body with connections for flow,
return, safety valve and drain
• As an option with inspection port on the water side
• Bottom rear inspection aperture on flue gas collector
• Boiler base frame for even load distribution and easy
transportation
• Large burner door closing on the left hand side
(can be changed to the right hand side if required)
• Air-cooled combustion chamber sight glass
The following options are possible:
• Control unit holder
• Also available as a unit version (with boiler and
burner)
• Heat exchanger as integrated or stand-alone version
with and without the use of condensing technology
