Light Oil Burner
Riello RG3 Light Oil Burner
The Riello RG3 is a light oil burner in the Riello programme, rated about 174 kW (150,000 kcal/h, light oil) for mid-size package boilers. The Riello Gulliver RG3 carries the Gulliver single-stage light-oil platform one step above the RG2 in output. It keeps the same compact Gulliver head and control philosophy, so service teams already know the commissioning routine. The RG3 lifts the Gulliver platform into the mid small-boiler bracket between the RG2 and the RG4S.
Why buyers choose it
- Rated about 174 kW (150,000 kcal/h, light oil) — matched to mid-size package boilers, not a generic catalogue figure.
- The RG3 sits between the RG2 and the RG4S in the Gulliver range, covering the mid small-boiler light-oil duty.
- The RG3 lifts the Gulliver platform into the mid small-boiler bracket between the RG2 and the RG4S.
- Backed by Riello authorized-distributor selection and commissioning support.
- Fitment: Because it shares the Gulliver flange and fan, the RG3 replaces an RG2 or RG4S mechanically with only a duty re-rate.
- 3-year warranty on complete units & core components, with pre-dispatch inspection.
- Pick the RG3 when the duty sits in the ~150,000 kcal/h light-oil band — it is the Gulliver model that fills the gap between the RG2 and the RG4S.
- The RG3 keeps the small Gulliver head, so existing RG2 mountings can be upgraded to a higher output without changing the boiler front.

Applications
Riello RG3 is specified for mid-size package boilers where light oil burner duty must stay stable across load swings.
Plants also fit the RG3 to thermal-oil heaters in the 150,000 kcal/h bracket, because its single-stage control keeps commissioning simple.
For food and textile plant hot-water loops, the RG3 is the Riello option that When an existing Gulliver mounting pattern is in place and only the output class must rise, the RG3 is the direct upward swap from an RG2.
Plants keep the RG3 when an RG2 throat already exists and only the duty class must rise.
On small and mid-size package boilers and light-oil thermal units, the RG3 is the common selection because its single-stage light-oil control is easy to commission and service.
