Product Description3

3 Product Description

The LT135/2 - 300/2 indirect fired domestic hot water

tanks are factory assembled with exception of screw-on

feet (packaged with the boiler) and piping accessories

(packaged in envelope with tank) to be installed in the

field.

The major components of the tank are:

– Tank vessel with corrosion protection

Corrosion protection is provided by hygienic Buderus

Thermoglaze "DUOCLEAN" as well as additional

cathodic protection using a magnesium anode rod

(Fig. 1, Item. 5), which is accessible by means of the

clean-out cover (Fig. 1, Item. 2).

– Clean-out cover (Fig. 1, Item. 2) for maintenance

and service access.

– Insulation (Fig. 1, Item. 3)

The insulation consists of high density polyurethane

directly attached to the tank vessel. An insulating

ring (Fig. 1, Item. 6) reduces heat loss from the

clean-out cover.

– Domestic water temperature sensor bracket (when

using Buderus Logamatic control) (Fig. 1, Item. 4)

The sensor is strapped under the clip on the clean-

out cover for temperature control when using a

Buderus Logamatic control. When using a

Honeywell aquastat (not furnished), the coupling and

immersion well supplied are connected to the EZ

connection on the back of the tank.

– Smooth surface heat exchanger

A smooth surface heat exchanger inside the tank

vessel transfers the energy from the boiler water to

the domestic water. The temperature in the tank will

be evenly distributed.
