General characteristics


RinNova Cond Plus is the new BIASI range of wall-mounted condensing boilers: excellent performance thanks to the new heat exchanger and ease of use thanks to the digital control panel with display. Available in versions for heating and domestic hot water production and for heating only RinNova Cond Plus presents a complete range of powers, 20 and 30 kW combi models and 16 KW SV models, in the same extremely compact dimensions (700 x 400 x 290 mm) .

RinNova Cond Plus has its strong point in the innovative heat exchanger designed to provide high yields that last over time digital control panel, designed to communicate with the user easily and conveniently. Like the entire BIASI condensing range, RinNova Cond Plus allows you to derive maximum savings from climate thermoregulation, based on the system in which the boiler is installed

Stainless steel plate sanitary exchanger
7 liter expansion tank
High efficiency pump with low energy consumption
Maximum power adjustable according to the system • IPX5D protection degree
Can be installed in a partially protected place
Integration with BIASI solar systems, using a solar kit
Digital control panel with backlit display
Analog pressure reading
Provision for remote control and external probe.

Control panel

Summer/winter/off selector
Heating temperature regulator
Domestic hot water temperature regulator
Analog pressure reading
DHW temperature and heating displayed
Display of fault diagnostics, lockout status and fault history
Recommended filling display and filling guide
Display of annual maintenance deadline
The display operates in the following ways:
1. INFO. Info mode displays the following information:
External temperature (in case of external probe connected)
K value (in case of external probe connected)
DHW/heating temperatures chosen by the user
Smoke temperatures.
2. PROGRAMMING. The programming mode allows you to modify the boiler parameters. - In chimney sweep mode it is possible to test the boiler and make adjustments to the gas valve.


By connecting the external probe and the remote control (optional) directly to the boiler you can take advantage of the climate regulation. RinNova Cond Plus will adapt the system water temperature to external climatic conditions, ensuring the desired room temperature is reached without waste and optimizing consumption. By using climate regulation, the regulation efficiency also increases, giving greater value to your home.

Highly regulated single-spiral primary exchanger

Biasi introduces to the market the new stainless steel heat exchanger for condensing boilers: Round. Round is a compact monothermal heat exchanger based on a stainless steel coil with an oval section. The heat exchanger consists of a combustion chamber, condensation area and an insulated metal disc protected with silicone ceramic fiber that separates the two areas. By using a single stainless steel strip to produce the coil, including inlet/outlet connections, the following advantages are achieved:

The accumulation of dirt and debris is avoided
The water flow rate is uniformly distributed and guarantees a homogeneous heat exchange
The water flow rate is constant for a longer product life
Reduction of pressure drops with optimized circuit.

The ease of cleaning and the robustness of this exchanger are one of the main strong points of the product given that it can be used on new systems but also on old systems in the event of renovations. Round integrates the round flow function in which the water produces a centrifugal cleaning effect on the internal walls of the single coil. The absence of parallel circuits guarantees an easy "washing" operation of the exchanger and the elimination of any air present in the system circuit.

All ready for Energy Labeling

What is it about?

From 26 September 2015 the European Commission directives regarding eco-design and energy labeling will apply.

These two directives aim to achieve savings in one of the most polluting and energy-intensive sectors: construction

For placing on the European market, the Eco-Design Directive ( ErP known as « Energy Related Products ») imposes a minimum energy efficiency for heating and hot water production devices in domestic premises. The directive applies to:

generators with a capacity of less than 400 kW
water heaters with a capacity of less than 400 kW,
kettles with a capacity of less than 2000 litres

As in the household appliances sector, the energy labeling of products with a capacity of less than 70 kW will give consumers simple, recognizable information that allows comparisons. on the performance and energy consumption of the product you wish to purchase.

The energy label will be included in all boilers, water heaters and kettles placed on the market from 26 September 2015.

Does it affect me too?

YES, it concerns everyone: professionals and end users

The information indicated on the energy label will allow professionals to recommend the right product and individuals to benefit from the information available.

The user will be able to easily compare the performance of the products.

From 26 September 2015 , the label will be present on the following products: boilers, electric water heaters, thermodynamic water heaters, solar water heaters, storage tanks, heat pumps, solar systems and control systems.

Supplier responsibility

The company that supplies the product on the market is required to equip its equipment or systems with the following documentation:

product energy label;
technical product sheet;
system energy label in addition to the product one, both in the case of selling a system that includes the product in question, and if this, in the future, can be sold combined with other additional devices;
technical data sheet of the system with the parts relating to the product or system already filled in.

Responsibilities of retailers

It should first of all be clarified that the reseller can be anyone who sells, rents, offers for rent/sale and displays an appliance and/or system to the public. Therefore, even professionals such as plumbers, installers or designers can fall into this category. Everyone is required to ensure that:

all devices and/or systems are equipped with their respective labels and ensure that they are clearly visible;
all devices and/or systems are always accompanied by the mandatory technical data sheets;
any type of advertising, promotional or technical material in which energy data or price indications are shown contains an indication of the energy efficiency class.

The new ErP regulations


Appliances for space heating and hot water production must be equipped with the new energy label which will report the energy class and main performance data. The energy class must also be cited in the technical, commercial and advertising documentation of the appliances.


The new ErP regulations impose the minimum energy efficiency that space heating and hot water production appliances must achieve to obtain the CE mark and be marketed in Europe. These new limits will exclude obsolete technologies from the market, significantly raising the level of energy efficiency of products.


Depending on the type of appliance, there are different labels. Those with efficiency classes A, A+ and A++ certify the products with the highest performance. Furthermore, two different classifications are envisaged for domestic heating and for the hot water production service, so much so that mixed products must show both classifications. The labels contain, in addition to the energy class, other information, so that the end customer can make his choice in the most informed way possible.


In addition to the product label, a system label is also provided if a series of combined equipment is offered. This label must also be included in the technical and commercial documentation of the system. Whoever proposes such systems will have to calculate the performance using a predefined calculation algorithm and display the label in order to inform the end user in the best possible way.
