Home for the Holidays – High Hot Water Demand

November 10, 2025

Rheem Holiday Essentials

During the holidays, your home transforms from a quiet weekday retreat into a bustling hub of activity. Guests are showering one after another, the dishwasher is running overtime, and the laundry pile triples thanks to extra towels, bedding and festive messes. That’s a lot of hot water, all at once, and if your hot water system can’t keep up, someone’s getting a cold surprise. That’s where ENERGY STAR® certified Rheem Maximus and FT-Series and ThermaForce® advanced boiler solutions save the day.

Maximus® is built for busy households, especially during high-demand seasons like the holidays. From continuous, back-to-back showers to endless laundry, Maximus heats water 2X faster and keeps it coming so your holiday hosting runs warm, smooth, and stress-free. When demand spikes, MaxMode boosts output by 15% to keep hot water flowing.

FT-Series and ThermaForce® tankless gas boiler solutions deliver scalable, high demand options to meet domestic hot water demands during the holidays. With combi boilers and boilers paired with indirect tanks, your friends and family will enjoy continuous, on-demand hot water. Plus, these super high efficiency technologies ensure you’re not left with big utility bills.

Quick Prep Tips Before Guests Arrive:

  1. Do a Quick Maintenance Check – Flush your water heater if needed, inspect leaks, and make sure everything’s running smoothly to avoid surprises during your hosting window.
  2. Check Your Water Heater Settings – Activate any high-demand modes like MaxMode to maximize output before guests arrive. For boilers, enable Domestic Hot Water (DHW) Priority and consider raising the set point if you have a mixing valve. You’ll need to check your mixing valve settings to ensure safe water delivery and scald prevention.
  3. Activate Your Recirculation Pump – If your system includes one, schedule your recirculation pump for no-wait hot water, especially in guest bathrooms.

Whole-Home Heating with Hydronic Air Handlers and Boilers

Pairing Maximus with a hydronic air handler delivers whole-home heating and continuous hot water, all from a single, efficient source. FT-Series and ThermaForce combi boilers and boilers paired with indirect tanks also give homeowners a space and water heating solution. That means fewer systems to manage, lower energy costs, and a home that stays warm and comfortable, even when the temperature drops and the guest list grows.

Ready to Host Without the Hassle?

Rheem’s commitment to innovation and reliability means you can focus on what matters most: spending time with loved ones. Upgrade to Maximus, FT-Series or ThermaForce and enjoy whole-home heating and continuous hot water, just in time for the holidays. Explore Maximus and Rheem Boilers online or talk to a Pro to see how these solutions can transform your home comfort.
