What to check before installing this boiler

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

  1. Confirm the model and commercial reference, the type of gas, and the supply configuration in the manufacturer's documentation.
  2. Ask a qualified installer to assess the heating and domestic hot water demand; compare measured flow rates at the same temperature difference.
  3. Check dimensions, connections, flue gas evacuation, condensate drainage, and controls compatible with the existing installation.
  4. 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 0T4D9AWA

Is it suitable for a large house of 300 m²?
Only if the loads and the system of the house justify its power. For example, 300 m² at 80 W/m² require 24 kW, which is below its maximum of 42.9 kW at 80/60 °C; therefore, the square meters alone are not enough to choose the 45 H over a smaller one. Its minimum of 6.3 kW at that regime also matters when few zones are operating. The example does not replace the calculation of the installation.
How is domestic hot water prepared?
The domestic hot water is prepared with an external accumulator connected via the sensor and the three-way valve provided for the system. The accumulator and its accessories are not deducted from the nominal power of the boiler.
Can it supply two showers at 8 l/min?
The boiler does not produce instantaneous domestic hot water. The result depends on the external accumulator, its volume, recovery, regulation, inlet temperature, and simultaneous use; the technical sheet of the boiler alone does not guarantee two showers.
Does it include a tank and what do the 350 liters in 10 minutes mean?
It does not include a sanitary tank. The 350 l/10 min stated in the table corresponds to the set with an external accumulator ECOUNIT of 200 or 300 l, not to the boiler alone or to a continuous flow of 35 l/min. The table does not specify temperatures for that data; it does not allow for guaranteeing a number of showers on its own.
What are the dimensions and weight?
The body measures 700 × 420 × 320 mm (height × width × depth) and weighs 35 kg. The final gap must include connections, drainage, service clearances, and the space for the accumulator.
What gases and controls does it include?
The technical sheet identifies G20, G30-G31, and a mixture of natural gas and hydrogen 80/20, as well as manufacturer control options. The configuration and commissioning must be defined by professionals; a specific control is not included.
Does the price include installation and shipping?
Includes VAT and shipping to mainland Spain. Installation and adaptations are valued separately. Heating only. Domestic hot water through external accumulator; expansion vessel not included.
