Proper Storage Tank sizing 2

[PAFred]

My water heater went up the other nite and I (having several women in the house) had to do something right then!
So I set out to obtain a replacement how ever at the time of night I was doing this the only thing I could come up with was a 85 gallon hot water heater (electric) which I bought and installed through the night. Then once done I decided to take a shower and clean up which brings me to the point. I noticed that the water pressure was a lot lower regarding water force that I had been acustomed to.
My water storage tank is only a 30 gallon REEM unit. I'm thinking that I am going to have to increase the storage tank size due to the volume size of the water heater, am I correct and if so what size should I put in or can someone recommend a web site that has this type of data?

Any time you get into the plumbing you can disturb the sediment in the lines, which end up in the little holes in the shower head or the flow restritor inside the head, or if the particals are large enough they can be trapped in the valve assembly. Alway run the bathtub to flush out any sediment after working on the plumbing. The bathtub is the only fixture without a flow restrictor for both hot and cold water.
Your storage tank sizing should have no relation to the volume in the hot water heater. The storage tank, I assume it is a hydropnuematic pressure tank, is generally sized on the flow rate of the pump according to a wide varities of rule of thumb.
Having a larger hot water heater will allow longer showers before getting cold water. Caution did you check the wattage of the new verses old heater to ensure proper wire size?

PAFred,
Size of water heater has nothing to do with the pressure in your water lines.
Your problem is probably related to clog in your water lines. If you have galvanized steel piping or piping that contains galvanized steel fittings, iron-oxide (rust) built-up may be the problem. There are number of products in the market that help you disolve this built-ups. Check your local hardware store.
Defected water heater dip tubes manufactured by perfection corporation and used in State water heaters between 93 and 97 might have caused your problem. This defected water heater dip tubes contain polypropylene that fail prematurely by disintegrating inside the water heater and eventually cloging the pipe lines. What was your previous water heater? If this is the problem I reccomend you to call a professional plummber to clean your pipe lines.
I hope this helps.
