Attic hot water loop.
The attic offers customizable and easily accessible space for improvements and modifications.
Even though the attic is well ventilated 2 fans lots of vents it can get very very hot well over 100 degrees on warm days.
In my case i decided to run both the supply and return loops close together with each line conventionally wrapped with foam pipe insulation about r 4.
The natural air flow created by a properly vented attic will move hot air out of the home.
We have a recirculating hot water system with a foam wrapped copper loop so it doesn t take forever to get hot water to the kitchen baths.
It works together with the attic insulation which will ensure hot air does not enter the attic from outside.
They have thermostats that turn the fan on at a recommended preset temperature of 100 110 degrees.
I am planning to install a hot water recirculation loop on my existing system to facilitate a frequent high demand for hot water in our kitchen.
While soft water will make the water heater happy along with all the fixtures on the hot side hard water is still in the system every inch of the cold side and where hot and cold meet at faucets.
A continuously operating pump is clearly wasteful.
Attic ventilation is vital to the upkeep of your home so make sure it is installed and functioning correctly.
Install electric ventilators and attic fans which remove hot air from an attic.
Alternatively install passive vents such as gable soffit and ridge vents which are openings in the roof that allow hot air to escape.
The only way water steam can get into the attic is through the central heating tank or the hot water storage tank either through the expansion pipe or the outlets of the storage tanks.
I am planning to run a 1 2 pex line into the attic and then back down into the closet where the hw tank resides.
However doing so in a way that doesn t waste a lot of energy is a little trickier.
A note on super insulating the hot water pipes of the recirculation loop.
Expecting to save a lot of energy and having safe hot water in our homes may at best be a compromise.
Primary loop piping is commonly used in boiler heating systems that run needing multiple temperatures or contstant temperature at the hydronic boiler is required.
Creating the loop is fairly easy.
Primary loop piping allows non condensing boilers to maintain a heat level in the boiler high enough to allow the boiler to run at its most efficient state.
My house is on a slab.
A hot water loop uses a small pump to circulate hot water between a water heater and a distant bathroom or kitchen.
The problem is the cold water.
The main use of a water loop is to keep the inside and outside of home s water systems separated.
The pump uses a lot of electricity and the heat losses.
