Installing a new water heater is a significant investment in your home’s comfort and efficiency. The installation process is just as crucial as the unit you choose, as it directly affects the system’s performance, lifespan, and safety. Installing a water heater goes beyond simply hooking up a few pipes. It requires a thorough understanding of local plumbing codes, manufacturer guidelines, and the unique environmental conditions of the Denver area.

A water heater is essential to your home’s mechanical system, and our team is committed to delivering reliable and long-lasting installations.

Why a New Water Heater Installation Is More Complex Than a Simple Replacement
Upgrading to a modern water heater involves more than simply replacing the old unit. Advances in energy efficiency and updated safety codes mean newer water heaters often come with changes in size, venting systems, and utility connections. For instance, high-efficiency models may be larger or shaped differently, requiring modifications to their installation space.
Transitioning between technologies, such as moving from a gas heater to a high-efficiency condensing model, introduces additional factors. The old metal flue may need to be replaced with PVC venting, and a new drain line might require condensation. Similarly, switching to an electric heat pump water heater requires adequate surrounding air to function effectively.
We begin by assessing your current setup and creating a clear plan to meet the requirements of your new system.

Code Compliance: The Key to a Safe Installation
Installing a water heater isn’t just about getting hot water into your home; it’s about doing it safely and in line with important plumbing codes. These local and national standards are designed to protect your property and the people in it, making code compliance a critical aspect of any water heater installation.
Thermal Expansion Tanks
For homes with closed-loop plumbing systems, a thermal expansion tank is a vital addition. It helps absorb the increased pressure created when water heats up and expands. Without it, this pressure could strain your plumbing, leading to leaks or damage to your water heater and pipes.
Drip Pans & Drains
A properly installed water heater must include a drip pan connected to a nearby drain. This setup catches small leaks and channels the water away, reducing the chance of water damage to the surrounding area. This simple addition provides a crucial layer of protection for your home.
Electrical Bonding & Grounding
Electrical safety is another key component. Proper bonding and grounding minimize the risk of electric shock by directing stray electrical currents safely away from your home’s wiring. This is particularly important for water heaters that operate with electricity or reside in high-humidity spaces like basements.
Seismic Straps
Seismic straps are critical for areas prone to ground movement, such as Denver. These secure the water heater to prevent tipping, which can cause significant damage to gas or water lines. This added stability is essential for reducing risks during unexpected events like earthquakes.
At Allen Service, we strictly abide by all Denver-area codes to deliver installations prioritizing safety and dependability. Adhering to these regulations, we help protect your home while providing the reliable hot water you need to stay comfortable year-round.

Strategic Selection: Choosing the Right Size for Your Water Heater
Selecting the correct size water heater for your home is critical to maintaining comfort and avoiding unnecessary energy expenses. An appropriately sized unit means you’ll have enough hot water when you need it without wasting resources.
Understanding Tank-Style Water Heaters
When considering a tank-style water heater, the First Hour Rating (FHR) is a more practical measure than tank capacity. FHR indicates how many gallons of hot water the unit can supply in an hour during peak usage, starting with a full tank.
To find the appropriate FHR for your household, consider the number of people in your space and their water usage patterns. For example, a household with multiple back-to-back showers while using dishwashers or washing machines will need a unit with a higher FHR to handle the simultaneous demand.
Key Factors for Tankless Water Heaters
Tankless water heaters work differently, requiring attention to flow rate (measured in gallons per minute, or GPM) and temperature rise. Flow rate represents the combined water demand of fixtures expected to run simultaneously, such as showers, sinks, or appliances. Temperature rise, on the other hand, is the difference between incoming cold water temperature and your desired hot water temperature. Given Denver’s typically cold groundwater, a unit with sufficient heating capacity is essential to avoid lukewarm water during heavy use.
By carefully evaluating these factors, you can make an informed decision and select a water heater that matches your needs, providing consistent comfort and efficiency for your daily routine.
