Can Bromic, Kosan or Cavagna gas regulators be used indoors?

Only our appliance regulators are for indoor use. All other gas regulators are for outdoor use only.

What are First Stage and Second Stage gas regulators used for?

First Stage and Second Stage gas regulators are used in domestic and commercial applications.

A first stage gas regulator is often connected to one or two gas cylinder/s with pigtail/s, taking the pressure from max. 1750kPa to approximately 70kPa. A second stage gas regulator is placed further along the gas line and takes the gas pressure from approximately 70kPa to 2.75kPa.

We recommend Kosan First Stage and Second Stage regulators for high-pressure and high-volume commercial applications.

What does the safety shut-off feature do on dual-stage regulators?

All Bromic and Cavagna dual-stage regulators comes with a patented safety shut-off feature.

The safety shut-off is a mechanism that will engage in the event of gas flow greater than 140% of rated flow (e.g. regulator diaphragm failure, equipment leakage downstream). This prevents any potential disasters and ensures safety at all times.

How does an electric jet pump work?

Jet pumps, also known as “pressure pumps” are water pumps that contains and drives an impeller/centrifugal pump. The impeller moves water, through the Jet Pump and increases the pressure of the water, to assist in areas where high suction lift is required (e.g. double storey homes)

Should I install a jet pump below or above the tank?

For water tanks including rainwater harvesting systems, Bromic Waterboy™ jet pumps can be installed below or above the tank.

Installing a water pump below the tank aids the water flow and hence has minimal installation requirements. If a Bromic Waterboy™ jet pump is installed above the tank, it should have a foot valve (not supplied by Bromic) installed at the bottom of the pipe in the rainwater tank. This is to prevent water from flowing back down to the tank.

What can Bromic Waterboy™ jet pumps be used for?

Bromic Waterboy™ jet pumps can be used for various applications.

This includes:

  • Residential wells
  • Aquariums
  • Garden irrigation
  • Domestic and commercial properties
  • Water tanks
  • Draining sump or well
  • Lifting or elevating liquids
  • Aeration or agitation
  • Boosting suction pressure to a centrifugal pump

How do I choose a water pump for my rainwater tank?

There are a few factors to consider when choosing a water pump for rainwater harvesting:

  • The type of pump (submersible or jet pump)
  • Required flow rate
  • Required head
  • Required pressure. Pressure for water can be calculated using P(kPa)=9.81xhead(m)

Contact your local plumber to size up correctly for each individual application.

Can I use a Heat-Flo ™ Blow Heater with Natural Gas?

Heat-Flo ™ Blow Heaters can only be used with an LPG cylinder and can not be converted for use with Natural Gas.

Which hose is supplied with a Heat-Flo ™ Blow Heater?

Each heater comes with a hose and regulator to connect to a 45kg cylinder. We do not provide any alternatives such as type 27, bayonet, or longer hoses.

Can you change or regulate the temperature on a Heat-Flo™ Blow Heater?

No. Each heater has a set gas input, so there is only 1 flame. If more or less heat is required, we have 4 different sizes available with different gas consumptions.
