When you hear hot water, you probably picture a storage water heater. The hot water system, however, is more than just the device that makes hot water. There are inputs, outputs, water heaters, and the distribution system. In this session, we'll start with an overview of hot water as a system and then look at two particular components of that system, heat pump water heaters and efficient hot water distribution.
Finding yourself compressor curious? Do you wish for a Tank Tinder? Help is on the way. Over the last few years there has been many lab studies, field studies, and customer satisfaction studies involving heat pump water heaters. These studies include the impact of lowering volumetric requirements, the actual in field performance of HPWHs, 120 HPWHs and the impact of exhaust only venting in colder climates. Hot water distribution: Too many people have to wait far too long for hot water to arrive at the tap. When you look carefully at flow rates, plumbing layouts, and pipe sizes, the reasons become obvious. In this part of the session, we will look at what's wrong with the distribution in so many homes and how to improve it.
Learning Objectives:
By attending this session, attendees will:
Name several of the inputs and outputs of the hot water system
Explain the impact of tank sizing on hot water loads and energy savings, how thermal mixing valves can be used to increase stored thermal energy, and how to achieve high levels of customer satisfaction with HPWHs
Describe how to analyze and fix the two biggest problems with most hot water distribution systems
