Stainless Steel Outer Cabinet Stainless Steel Water Tank Very High Quality Insulation for maximum economy - essential in these days of never-ending electricity price increases! Digital Controller to maximise electricity savings by heating during "economy-7" periods Dual-Outlets (70 gallon and larger) allow for two washes between re-heat cycles Stainless Steel Fittings Stainless Steel Immersion heater element (Incoloy) Also available with side mounted header tank MASSIVE SAVINGS IN ELECTRICITY COSTS! Our heaters are equipped to heat up during the "off-peak" period, saving up to 75% of electricity costs.  Also available in wall-mounted versions Being of all-stainless-steel contruction, Cotswold Dairy Water Heaters are guaranteed against corrosion and can be relied upon to give very long service. The fully insulated internal tanks are fitted with a 1¼" BSP stainless steel drain outlet (1½" BSP on 200 gallon and larger sizes), stainless-steel outlets and overflows, and stainless steel elements. The inner tank is square, ensuring maximum capacity in minimum space. Most models include a time clock, graduated in 15 minute intervals, as well as manual over-ride button and indicator lamps. A thermometer calibrated in centigrade degrees is also fitted. An automatic vacuum switch ensures that no cold water can enter whilst the farm vacuum pump is in operation. Economy models are available, built to the same high standards but with ball-valve feed in place of the solenoid valve.

Heat Recovery Models are available, using the temperature of the hot gas produced by the dairy refrigeration system to pre-heat the water. Water heaters can be supplied with a variable level stainless steel float switch. This allows the amount of water to be heated to be changed very easily. Dual outlets are recommended (standard on 80 gallons and above), to take advantage of off-peak electricity. Various types of controller are available, from simple ball-valve to sophisticated electronic systems using timers, level controllers and microcontrollers. ESSENTIAL INFORMATION - WATER HEATER INSTALLATION Cotswold Water Heaters are fitted with back-mounting bars, but, due to their weight when filled, under-support is also necessary. Load-bearing stands for all models are available from Cotswold. When heaters are installed in a loft, please ensure that adequate support for a fully-filled tank is provided. Our water heaters are normally gravity-fed, therefore the water outlets should be above the water trough unless it is intended to empty the water heater using the plant vacuum or a pump. In hard water areas, it is essential that a scale preventer and a water strainer are fitted. These help prevent scale forming inside the water solenoid valve and around the heater element. The cost of these inexpensive devices will soon be recovered from reduced electricity charges. Claims under warranty for damage or failure caused by hard water and/or installation of the equipment to an unssuitable water pressure will not be accepted unless the use has taken sensible precautions. If you are in doubt please speak to Cotswold or your dealer. IMPORTANT The cold water inlet is controlled by an electrically operated solenoid valve suitable for water pressures of bewtween 0 and 150 PSI, (0-10 bar). Should your water pressure not be within this range, please ask at the time of ordering and we will supply a water heater with an alternative valve suitable for the pressure specified.
	FLOOR STANDING WATER HEATER WITH SIDE MOUNTED HEADER TANK PROBLEM: Your Hot water becomes progressively less hot as the milking cycle progresses CAUSE: Cold water is being admitted to the hot water tank as hot water leaves, and this cools the remaining water SOLUTION: Do not admit any cold water until all of the hot water is used. Only then should you refill the tank and heat water for the next milking cycle. COMPLETE SOLUTION: Invest in a newly-introduced Cotswold Water Heater with side-mounted header tank  The header tank contains a ball-valve feed system with vacuum-operated clamp valve cut-off. This prevents cold water entering the tank whilst the plant vacuum pump is running (ie whilst milking is in progress). BENEFITS:   A complete tank of hot water is available, which will NOT be cooled by  incoming cold water until the plant vacuum is turned off at the end of the milking . OK - it's not entirely new, but a Cotswold Water Heater:- is of all-stainless-steel construction - (no residential-style copper cylinders) has heating elements of long life "Incoloy" which will last for many years has a fully-insulated rectangular tank, making best use of the space available utilises strong brass ball valve, not plastic type utilises electronic control to minimise electrical consumption is exceptional value, yet costs no more than existing models SIZE The side mounted header tank adds 160mm (6.3") to the width of the standard or economy model to which it is fitted.           Sizes of standard and economy water heaters.
