Read the full description and what it includes.

The Baxi Neodens iPlus 33/33 F boiler is a wall-mounted instantaneous mixed boiler with a nominal output power of 28.0 kW for heating at 80/60 °C, 30.6 kW at 50/30 °C, and 31.0 kW nominal output for domestic hot water. In hot water, it delivers 17.8 l/min at ΔT 25 °C and 12.7 l/min at ΔT 35 °C.

The main production of domestic hot water is instantaneous through an integrated plate heat exchanger; micro-accumulation improves the initial response. The body measures 700 x 395 x 285 mm and has an 8 l expansion vessel for heating. The installation is wall-mounted and the regulation allows for modulating control, OpenTherm, and BAXI CONNECT through the provided connections.

Guide

What to check before installing this boiler

The choice of equipment does not replace the inspection of the installation by a qualified professional.

Confirm the model and commercial reference, the type of gas, and the supply configuration in the manufacturer's documentation.
Ask a qualified installer to assess the heating and domestic hot water demand; compare measured flow rates at the same temperature difference.
Check dimensions, connections, flue gas evacuation, condensate drainage, and controls compatible with the existing installation.
Confirm the included accessories and the delivery time before scheduling the installation. The online purchase of the equipment does not include installation or commissioning.

Frequently Asked Questions

Frequently asked questions: condensing boilers 7886910

Can it supply two showers of 8 l/min at the same time?

With two showers of 8 l/min (16 l/min) and inlet water at 10 °C heated to 45 °C, the temperature difference is ΔT 35 °C. This variant delivers 12.7 l/min, so it is not sufficient to maintain two simultaneous showers of 8 l/min under those conditions. For a single shower of 8 l/min, there is available flow; the inlet temperature and network pressure determine the actual result.

Is it instantaneous or does it have a domestic hot water storage tank?

The main production of domestic hot water is instantaneous through an integrated plate heat exchanger. Micro-accumulation improves the initial response but does not replace a large-volume storage water heater. The 8 l expansion vessel belongs to the heating circuit and does not store water for showers.

What are its dimensions and how is it installed?

The unit measures 700 x 395 x 285 mm (height x width x depth). It is installed on a solid, smooth, and vertical wall, using its wall bracket; two people are needed to lift and hang it. The fastening, connections, and clearances depend on the installation and the flue adapter, so these should be carried out by a professional.

How does it modulate and what controls does it support?

The flow temperature is automatically adjusted with a modulating thermostat, OpenTherm or BAXI CONNECT. It also supports R-Bus, OpenTherm, and room thermostat connections; the pump modulates from 85% to 100% in heating and operates at a fixed 100% in domestic hot water.

What gas does it use?

For Spain, work with category II2H3P, G20 (natural gas) or G31 (propane). The gas configuration and checks must be adjusted to the installation and applicable regulations by qualified personnel.

Does the price include installation and shipping?

Includes VAT and shipping to mainland Spain. Installation and adaptations are valued separately. With support and horizontal flue kit 60/100 (140040191). Installation not included.
