Are the manufacturers and patient holder of SPEEDHEAT water heaters. SPEEDHEAT has been tested and approved to the European Standards IEEC 335-1, IEEC 335-2-35 and BS EN 335-1:1988, and have been designed with a sheathed element for use in all normal water conditions. Plastigo c.c is an accredited ISO 9002:2000 manufacturer.

water heaters. Are available in 3kW, 3.5kW and 5kW models. Various attachments are available. Saves electricity and water consumption. Is cheaper and easier to install, compared to an electric boiler/geyser. The element can be cleaned or replaced if there is a calcium build-up on it. Is fitted with a thermal cut out switch. (A safety feature which switches off the element should the water get too hot) This prevents the element from burning out. Can be used in a low water pressure areas, it requires a minimum of 50 kPa, to operate. Carries a 1-year manufacturers warranty.

COST EFFECTIVENESS OF SPEEDHEAT vs. ELECTRIC BOILER

SOUTH AFRICAN electricity costs: R0.28 kW / Hr (Check this cost in your area)

Using a 5 kW unit, the electricity costs for a family of 6, with each person showering for 5 minutes a day +/- R 21.00 per month

(R0.28 per kW/ hour) = R0.28/60 = R0.004666
R0.00466 x 5kw x 6People x 5minutes = R0.70 / day = R 21.00 per month.

Compared to cost of maintaining the heat to an electric cylinder/ boiler/geyser
Standard heat loss formula for a 150 liters boiler = 0.4watts per liter + 60 watts
Cost per hour to maintain boiler at temperature = (0.4w x 150 liter)+ 60w = 120w
At current cost of * R0.28 kW / Hr * = 0.120w x R0.28 = R0.0336 / Hr
24hrs x 365days = 8760hrs per annum = R 0.0336 x 8760 = R294.34 p.a.
Losses from the boiler " geyser" only, = R 24.53 per month

NOTE: This excludes the cost of showering as in the calculation. There are other costs when using a "geyser", this is when the tap is situated some distance from the boiler and when hot water is left to cool in the pipes after the hot tap is used.

There are savings all round when installing a SPEEDHEAT. A conventional water storage heater "geyser" costs more, installation costs are much higher, it will consume five times more electricity and water.

Procedures for demonstrating a

1. Attach the rubber (Gardena) connector to a cold-water tap.
2. Connect the hose, which is attached to the Speedheat to the above.
3. Fit the 15-amp plug, connected to the cable from the Speedheat into the plug socket. Keep the power off for the moment.
4. Holding the unit with the electrical cover to the top, open the tap allowing a good flow of water. Switch on the power and within 15 seconds the water will be getting hot.
5. Slowly reduce the flow of water to achieve the desired temperature.

Note: A 5 kW unit will draw 22 amps of electricity thus requiring a 25-amp circuit breaker. Should the plug socket being used for the demonstration be protected by a 15-amp circuit breaker, it may trip. Try it to see if it works, if it is demonstrated for a short period of time, sometimes you can get away with it. This is not recommended for the proper installation. Please read the instructions supplied with the unit.

In a proper installation the unit will be connected to the DB. The power to the unit can remain switched on, even when not being used. Only when the water is flowing through the unit will the element switch on.
