General

NIBE UKV 20 is an accumulator tank that is suitable for
connection to a heat pump or other external heat source.

NIBE UKV 20 can have several different areas of applica-
tion, and can be used during external control of the
heating system.

The heat pump then charges NIBE UKV 20 with floating
or fixed condensing. The external control function con-
trols the heat distribution from NIBE UKV 20 to the con-
sumer. If the flow to the heating system can be restricted
using radiator thermostats, for example, install a
NIBE UKV 20 as an intermediate tank. This ensures a se-
cure flow for the heat pump. NIBE UKV 20 also allows a
greater flow to the heating system than across the heat
pump. In some installations, so-called heat spikes occur
as a result of movements during temperature changes.
To eliminate temporary temperature changes, and
thereby prevent heat spikes, install a NIBE UKV 20 after
the heating installation.

The water tank consists of a high-quality steel jacket, the
outside of which is coated with rust-protection paint.

UKV 20-500 is designed and manufactured for a maxim-
um cut-off pressure of 6 bar in the water tank. UKV 20-
750 and UKV 20-1000 is designed and manufactured
for a maximum cut-off pressure of 3 bar in the water
tank. Maximum permitted temperature is 85 °C. All
NIBE UKV 20 are equipped with a temperature gauge,
which can be installed at various levels in the accumulat-
or tank.

UKV 20-750 and UKV 20-1000 are equipped with a
special pressure gauge. This gauge is located on the left
side of the accumulator tank and is tasked with prevent-
ing the stratification of the water in the accumulator
tank.

The insulation is polyurethane, which provides excellent
heat insulation. The insulation and grey plastic outer
cladding can be removed to make it easier to move the
water heater through doorways, for example.

NIBE UKV 20 is equipped with an immersion heater
socket and a submerged tube for controlling hot water
heating.

UKV 20-750 and UKV 20-1000 can be equipped with an
immersion heater and UKV 20-500 can be equipped with
up to two immersion heaters.

Transport

NIBE UKV 20 should be transported and stored vertically
in a dry place. The NIBE UKV 20 may, however, be care-
fully laid on its back when being moved into a building.

Assembly

NIBE UKV 20 must only be installed vertically.

The accumulator tank must be installed in a dry area at
a temperature that does not drop below 0 °C.

Position NIBE UKV 20 on a firm base that can take the
weight, preferably on a concrete floor or foundation.
Use the product's adjustable feet to obtain a horizontal
and stable set-up.

Ensure that there is sufficient space to perform servicing
and maintenance.
