Gas May Lower Bills in Shed


FARMERS can now use gas- powered systems to heat the water in their dairy sheds, thanks to the efforts of a Taranaki man.

Steve Scott, of New Plymouth company Rivet, has joined forces with gas hot water specialists Bosch NZ to produce the gas hot water system for use on farms.

The two have been trialling the system for the past year and the product was launched at the Fieldays last week.

Bosch rep Vicki Rowland says the system is cost effective.

"I think farmers are looking for more efficient water systems. It is a positive for the industry. The temperature must reach 85 degrees Celsius. It will save thousands of dollars."

Mr Scott has built gas fitted tanks that are also solar ready, should farmers want to incorporate the sun's energies as well.

"They are run on LPG cylinders or they could be hooked onto the network. We had a Hawera sale today. He will go straight on to the gas," Mr Scott says.

The system has been designed to provide efficient, reliable hot water when the farmer requires it.

Traditional electric storage hot water systems are slow to heat up, have high heat loss and are a major component of the farm electricity bill.

The Rivet systems are flexible and can be installed as individual components or fully integrated with each other, combining the cylinder, drop tank, solar collectors and gas boosters. This flexibility allows the system to be installed in new and existing sheds, internally and externally.

The hot water systems and drop tanks are manufactured from stainless steel and made in New Plymouth.

The system is fully commissioned at completion of installation.

The cylinders are available in two sizes, 380l and 500l.

Mr Scott says costs can range from $16,000 to $25,000, depending on plant in the shed.

Bosch says until the introduction of the Bosch 32 there has been no suitable gas water heater to deliver the power and temperature to 85 degrees C without using storage.

One of its biggest benefits is it is faster and cheaper than electric heating.
