ROTEX air-to-water heat pump

Heating and cooling with

air, sun and ROTEX

The inexhaustible heat source on your doorstep

The sun is our natural energy provider. Take advantage of

this free heat supply and use it in your own home. It can be

found in environmental heat from the air or taken directly from

sunlight. This energy source is both free and inexhaustible.

The ROTEX HPSU monobloc utilises the environmental energy

available to supply heat to your house with maximum

efficiency.

ROTEX HPSU monobloc

With the ROTEX HPSU monobloc, all hydraulic components

are integrated into the outdoor unit.The compact unit is also

supplied with a fully sealed unvented cooling circuit, so that

the heating pipes run directly from the heat pump into the

building. Because connections are only necessary on the

water side, installation of the heat pump is exceptionally

straightforward and rapid. Only the thermal store and the spare

immersion heater (if applicable) need to be integrated into the

building.

The perfect choice for new build

The amount of heating energy required by modern buildings

is decreasing, and the required flow temperatures are lower,

too. This is where the low temperature ROTEX HPSU monobloc

heat pump comes into its own, be it in conjunction with low

temperature radiators or an underfloor heating system. The

advantage of underfloor heating is that, due to the extremely

large heating surface, it can make do with a low surface

temperature. Plus, it can even cool the rooms during summer.

„We knew from the start that a heat pump would

be the right choice for our new house. What we

didn‘t know was that the installation would be so

easy. With this appliance, ROTEX has produced

something so compact you barely notice it‘s there.

It‘s nice to feel that we made the correct decision.“

Inga and Ben Braun, proud homeowners

How it works

The ROTEX HPSU monobloc air-to-water heat

pump “pumps” heat from the ambient air into

the heating system with the help of a highly

efficient compressor. This principle is compa-

rable to using a refrigerator or air condition-

ing system in reverse and has already proven

its worth in millions of installations on the

European market.

Excellent package label ratings

Hooking up a solar thermal system is the most effective way to

reach a higher overall system efficiency class. The ROTEX Sani-

cube thermal store is already optimised for hooking up with a

solar thermal system, and provides the ideal complement to

the ROTEX HPSU monobloc. When linked up to a ROTEX Solaris,

this system will become your own personal ‚solar heater‘. The

integral central heating backup and large storage volume will

raise your system‘s energy efficiency ratings for both domestic

hot water and space heating.

Strong system solution:

Heat pump and solar

Safe in the knowledge it‘s ROTEX

All ROTEX products are tested and meet the criteria in the

Ecodesign Directive. For both individual products and pack-

aged solutions, energy labels are a reliable indicator of

efficiency class.

Perfectly matched in terms of their individual components, our

complete systems provide both maximum convenience and

the highest safety standards.

Efficiency made transparent

Energy efficiency labels for

heating systems

We‘re familiar with these labels on

fridges, televisions and other electri-

cal appliances. From September 2015,

heat generators and water heaters

will bear their own EU energy efficien-

cy labels. These labels will make it easier to compare individual

heating products and decide which ones to buy.

How the energy efficiency classes are determined

The product‘s seasonal energy efficiency will determine its en-

ergy efficiency class. Put simply, this indicates the relationship

between the total energy input and the useful heat output. The

greater the proportion of renewable energy used to generate

heat, the higher the efficiency class. As a result, heat pumps are

usually in the top efficiency classes (A+ and above), followed

by gas and oil condensing boilers, with conventional boilers

bringing up the rear, as they tend to perform comparatively

poorly against the relevant criteria.

Efficiency classes for products and systems

Individual heat generators will each bear a product label.

The efficiency of a heating system depends not only on the

heat generator, but on several components. That is why the

combination or package label was introduced. This covers the

heat generator plus other components such as the controller,

cylinders, solar thermal systems and/or an additional heat gen-

erator. The combination label is calculated from the efficiency

values of the individual appliances and devices.

Expert advice

Every building is different. Your choice of a new heating system,

especially as part of modernisation, should not be based solely

on the efficiency rating. Depending on the characteristics of

your building, a heating system with a low efficiency rating

may consume less energy than a system with a higher rating.

Consequently it‘s important to get expert advice and help with

sizing: that‘s where your ROTEX partner comes in useful.

ROTEX air-to-water heat pump

ROTEX monobloc - all-in-one

The ROTEX HPSU monobloc air-to-water heat pump for out-

door installation combines all components in a single compact

unit. This unobtrusive appliance can be sited outside the build-

ing. When combined with a hygienic ROTEX thermal

store, it ensures optimum heating and hot water convenience.

Optimum water hygiene – maximum convenience

The water is heated in combination with a hygienic ROTEX

thermal store. Thus, you get maximum comfort for heating and

hot water.

Perfect climate: Heating in winter – cooling in summer

The HPSU monobloc can not only provide heating but can

optional also cool if required in rooms with underfloor

heating or a fan convector. Your feel-good climate in every

season.

Economical and quiet thanks to output modulating

operation

The heat demand of a building varies very widely depending

on weather conditions and utilisation patterns. The ROTEX

HPSU monobloc heat pump employs inverter technology,

which operates the compressor variably. In other words, the

output of the heat pump is continuously adjusted to meet the

demand.

Think DHW hygiene when

buying a heating system

ROTEX HybridCube - the hygienic thermal store

The ROTEX thermal store is a combination of domestic hot wa-

ter tank and instantaneous water heater. The heat is not stored

in the domestic hot water itself, but in the clearly separated

tank water. Optimum tank stratification ensures that the provi-

sion of hot water is always guaranteed.

The drinking water is contained in a high-performance heat

exchanger made of durable stainless steel (INOX). Your drinking

water remains perfectly hygienic.

The storage tank water is added at commissioning and

serves only for thermal storage. It is not exchanged and

consumed. The inner and outer walls are impact-resistant

polypropylene, the space in-between is filled with highly

heat insulating foam. This results in very good heat insulation

values and minimum surface losses.

The first thing we need for foodstuffs is clean water

The hygienic ROTEX thermal store principle:

The domestic water to be heated is conveyed and heated through a separate high-

performance heat exchanger made of stainless steel. Water that is charged first is

also the first to be removed (first-in first-out principle).

Solar systems by ROTEX

ROTEX Solaris: 2 possibilities - always the first choice

ROTEX Solaris is available in two different variants, that meet

all structural conditions and individual requirements.

1. The pressurised solar system (Solaris-P)

The pressurised solar system impresses with its simple

installation and is suitable for all applications and buildings.

It operates efficiently and safely at any desired length of pipes

and feed height. The well-engineered structure of the ROTEX

solar thermal store means that an additional plate heat

exchanger is not required. A bivalency heat exchanger for pres-

surised solar or other heat sources is already incorporated.

That makes the system simple and flexible.

2. The direct Drain-Back system (Solaris-DB)

If the constructional conditions permit, we recommend the

unpressurised and direct Drain-Back system. The water in the

store is supplied directly and without heat exchanger to the

solar panels, heated and then stratified into the store. This

considerably increases the efficiency of the solar collectors

and the entire utilisation of the installation. Since the system

is unpressurised, components which would otherwise be

required are not necessary, such as the expansion tank,

pressure relief valve, pressure gauge and heat exchanger.

The Solaris solar panels are only filled if there is enough heat

from the sun and if the thermal store can absorb heat.

The fully-automatic control system controls the system

independently to provide optimum utilisation of the solar

energy. If the sunshine is insufficient, or if the solar thermal

store does not need any more heat, the feed pump switches

off and the entire solar system drains into the thermal store.

The addition of antifreeze agents is not required since the

panel surface is not filled with water when the system is not

operating. This is a further plus from the environmental

perspective. The principle functions only if the connection

pipes in the building and on the roof are installed with a

constant gradient. If this is not possible, the pressurised solar

system is the optimum alternative.

ROTEX Solaris solar panels - flexible assembly

The Solaris solar panels convert almost all of the shortwave solar radiation into

heat through their highly selective coating. The three different solar panel sizes

mean there is flexibility in adapting to roof characteristics. Since all buildings

are different, there are various installation options for fitting the ROTEX flat solar

panels onto the roof. The solar panels can be fitted onto the tiles (on-roof ),

into the roof (in-roof ) or also with a special substructure onto a flat roof.
