Producing Hot water

BEST METHOD OF PRODUCING HOT WATER

With the recent rise in natural gas prices, it has become very important to look at new and existing buildings and evaluate how the buildings water is to be heated. Jails and prisons for example, spend more money on water heating than they do on heating /cooling or lighting. With this in mind, Hydro-Temp 's unique method of heating a buildings hot water can play a very important roll in lowering the cost of a buildings utilities.

On February 10, 1981, Hydro-Temp Corporation received patent # 4,249,390. This patent was awarded because of the unit's ability to transfer 100% of a buildings unwanted heat (during the cooling cycle) into the buildings hot water tanks. During the past 20 years we learned in many cases we could produce 100% of a buildings hot water at no cost. In order for this to occur it is important that our priority water heating system be installed on a unit that does a lot of cooling, during both summer and winter. Normally a unit that provides heating and cooling for a kitchen or an internal area of the building will work best. If hot water heating is needed when no cooling is being done that’s also okay. Our patented priority system will turn itself on in the water-heating mode and produce hot water at approximately one fourth of the normal cost of heating water.

Hydro-Temp drawing H001809B illustrates a common method of tying the unit's priority water system into a buildings hot water storage system. ( Drawing H000032 shows the same thing in a residential home ) It is important to note that purchasing smaller 50 or 80-gallon water heating tanks can dramatically reduce hot water storage tank cost. These tanks can then be plumbed in parallel to create the amount of storage needed. Drawing H000026 illustrates the same thing with one standard hot water tank. Drawing H002813 illustrates this with one Marathon hot water tank.

In the drawing, cold water is pumped from the bottom of the hot water tanks (A) through the priority water heating system where it is heated. This heated water is then returned to the tanks via cold water lines where it returns to the bottom of the tank and is allowed to rise to its own heated level. By using this method the entire tank can be heated from top to bottom, storing more hot water. Once this water is heated it is then available to feed tanks (B). Unlike tanks (A), tanks (B) have their electric elements powered. The function of these electric elements is only to replace the heat lost from the water tanks into the buildings through normal heat loss. The buildings hot water is being totally produced by the Hydro-Temps priority system. It is important to note that the electric elements that are powered are only 4.5 K.W. (one per tank). It is not uncommon for our company to replace hot water tanks that have electric elements totaling over 100 K.W.
