Water heating is a complex topic that combines in-home energy use with fuel choices, maintenance and water conservation… not to mention the discomfort of running out of hot water.
This topic demands detailed study to avoid wasting money every day you use hot water and having a system that fails to meet your expectations. We separated water heating + distribution from our plumbing course to have time to address your choices for and concerns about capacity, appliance types, safety and cost.
We’ll walk you through the following so you can make informed decisions about water heating and distribution in your home:
- What are the minimum (building code) requirements for water heating?
- What types of water heaters are available for homes?
- What type of water heater fits the needs of your household?
- What are the concerns with natural gas or propane water heaters?
- What are the concerns with heat pump water heaters?
- Can air conditioning and water heating systems be combined?
- How can you calculate the water heater capacity you need?
- How to deal with high-capacity needs: garden tub, “car-wash showers”, etc.?
What types of pipes? - What types of distribution systems are available?
- What type of recirculation systems are available?
- How does water heater placement affect distribution?
- How can we calculate wasted water for a plumbing fixture?
- Do pipes and water tanks need to be insulated?
As always, we’ll make our review in terms you can understand and use when speaking with contractors, home inspectors, etc. We invite your questions as we go so we can be sure you get the most value out of this course.
Register now and plan to join us for a live discussion of water heating and distribution. We welcome your questions as we go. We look forward to seeing you in our Zoom presentation from 10 AM to 12 PM Eastern on December 18, 2025!
