2.3.7.6 INTEGRATION IN A HEATING SYSTEM
Please note: The Senso M H
2
O / Piko H

O must only be installed after detailed
planning of the overall heating system in accordance with the relevant rules
of technology and the safety standards. Proper configuration of the pumps,
fittings, pipeline, buffer tank and the safety components is the responsibility
of the planning firm and/or of the company in charge of installation. For
heating lines, we recommend a minimum nominal diameter:
copper pipe of 22 x 1.0 mm, or 3/4" for steel pipe.
With cold water pipes, a pipe diameter (copper pipe) is 15 x 1.0 mm and a
flow pressure of 2.0 bar is sufficient for safe operation.
However, dimensioning of this pipework must be carried out by the specialist
company in charge, taking due account of on-site conditions.

O can be carried out based on the

on the next page.
A buffer tank must be connected up. German legislation 1st and 2nd BImSchV
mandates the design of volume for this buffer tank. This regulation specifies
that for each kW water capacity, at least 55 liters of buffer volume must be
kept.

For the Senso M H
2
O, these are: 5.0 kW x 55 litres / kW = 275 litres.
Piko H

O
For the Piko H
2
O, these are: 4.6 kW x 55 litres / kW = 253 litres.
Since these are not normal market sizes, the next larger buffer tank should be
chosen with 300 or 500 litre capacity.
