Ferroli Bluehelix Hitech RRT 28 C boiler

VAT includedIn stock

The Ferroli Bluehelix Hitech RRT 28 C combines heating and domestic hot water through a plate heat exchanger. It offers from 3.4 to 24 kW at 80/60 °C and from 3.8 to 26 kW at 50/30 °C. In domestic hot water, it claims 28 kW and 16.1 l/min at ΔT 25 °C; at ΔT 30 °C, the declared flow rate is 13.4 l/min. Compared to the 24 C, it increases the sanitary flow rate without enlarging the casing of 700 × 420 × 320 mm. It is an intermediate option when more hot water is needed, although it does not reach two simultaneous showers of 8 l/min at ΔT 30 °C. With standard flue kit. Installation, fittings, and Connect control not included. VAT and mainland shipping included.

Guide

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: calderas de condensación 695S00284

Is it suitable for a 150 m² house?
The surface area alone does not determine the model. For example, a calculated demand of 80 W/m² in 150 m² requires 12 kW, within the range of 3.4 to 24 kW at 80/60 °C. That assumption should be replaced by the actual load of the home; it is not a recommendation of square meters from the manufacturer. The choice against the 24 C may come from the higher flow rate of domestic hot water.
What improvement in hot water compared to the 24 C?
At a ΔT of 30 °C, it delivers 13.4 l/min compared to 11.7 l/min at 24 °C: 1.7 l/min more. At a ΔT of 25 °C, it goes from 14 to 16.1 l/min. It maintains the same dimensions, but it does not convert any installation of two bathrooms into a system suitable for two simultaneous showers.
Can it supply two showers at 8 l/min?
At 35 °C, it reaches 16.1 l/min from 10 °C, but at 40 °C it drops to 13.4 l/min; for two showers of 8 l/min at 40 °C, it is insufficient. The inlet and outlet temperatures are an example that applies the declared flow rates at ΔT 25 and 30 °C; the available pressure and flow must also be checked.
Does it have a domestic hot water accumulator?
Produces instantaneous domestic hot water using a plate heat exchanger, without a storage water heater. The expansion vessel belongs to the heating circuit and is not equivalent to a domestic hot water accumulator.
What are its dimensions?
The body measures 700 × 420 × 320 mm (height × width × depth). Space must also be reserved for connections, drainage, support, and maintenance.
What gases does it accept?
The technical sheet identifies G20 at 20 mbar and G31 at 37 mbar. The configuration, conversion if applicable, commissioning, and checks must be carried out by authorized professionals.
Does the price include installation and shipping?
Includes VAT and shipping to mainland Spain. Installation and adaptations are valued separately. With standard flue kit. Installation, fittings, and Connect control not included.
