How to Upgrade Your Hot Water System with Andrews Water Heaters
Upgrading a commercial hot water system is a big decision that can significantly improve operational efficiency, reduce energy consumption, and enhance service reliability. Whether you're managing a hotel, hospital, school, or industrial site, investing in modern hot water systems pays off over time. When considering a commercial water heaters upgrade, Andrews water heaters stand out for their durability, advanced technology, and trusted performance.
This guide will walk you through the process of upgrading to Andrews water heaters and provide practical insights on choosing the right model, planning installation, and ensuring your new system delivers lasting value.
Why Upgrade Your Existing System?
Old or inefficient hot water systems often struggle to meet modern performance expectations. Ageing components, heat loss, slow recovery rates, and rising utility costs are all signs that your system is due for an upgrade.
By moving to a more efficient solution, such as Andrews commercial water heaters, you'll benefit from:
- Faster hot water delivery
- Improved energy efficiency
- Lower operational costs
- Better compatibility with renewable energy systems
- Enhanced compliance with environmental standards
A system upgrade also improves occupant satisfaction, particularly in sectors like hospitality or healthcare, where hot water reliability is critical.
Assessing Your Current Setup
Before making the switch, it's crucial to evaluate your existing system. Determine the daily hot water demand, identify any performance issues, and review historical maintenance records. A thorough system assessment will help guide the selection of the right replacement.
Consider the following:
- Is your system meeting current hot water needs?
- Are there frequent breakdowns or high maintenance costs?
- Is the recovery time too slow for your building's usage pattern?
- How old is the existing water heater?
If your current heater has been in operation for over a decade, it's likely operating at reduced efficiency and increasing your running costs. Upgrading to a newer system from Andrews can yield significant savings and operational improvements.
Selecting the Right Andrews Water Heater
Andrews offers a comprehensive range of modern hot water systems designed for commercial use. From compact wall-mounted units to large-capacity floor-standing models, each solution caters to different building sizes and hot water demands.
When choosing a model, consider:
- Flow rate and peak demand
- Space availability for installation
- Integration with existing systems (e.g., boilers, BMS)
- Energy source (gas, electric, solar compatibility)
The Andrews range includes high-efficiency condensing water heaters ideal for businesses looking to cut energy usage while maintaining powerful hot water delivery.
Consult with the team at National Pumps and Boilers for expert advice on choosing a product that aligns with your building's operational needs.
Designing for Efficiency and Performance
A commercial water heaters upgrade isn’t just about replacing old units; it’s about designing a solution that enhances efficiency. With Andrews systems, features like modulating burners, high-efficiency condensing technology, and robust insulation come as standard.
Additionally, pairing your water heater with expansion vessels, pressurisation units, and DHW pumps ensures your hot water system performs at its best under varying demand.
You can also install commercial circulators for balanced water distribution throughout the building, ensuring immediate hot water access at every outlet.
Planning the Installation
A well-executed installation ensures long-term performance. Consider factors like installation timing, downtime requirements, access to mechanical rooms, and integration with pipework and controls.
Installation tips:
- Schedule upgrades during off-peak periods to minimise disruption
- Prepare the space by clearing access and ensuring ventilation compliance
- Confirm compatibility with building management systems (BMS)
- Test electrical and gas connections before commissioning
Work closely with certified professionals who understand Andrews systems and can provide post-installation support.
Incorporating Renewable Energy Sources
Modern hot water systems from Andrews are compatible with renewable technologies. If your building uses solar thermal panels or heat pump systems, an Andrews unit can integrate seamlessly to provide reliable backup heating and boost overall energy efficiency.
This hybrid setup significantly lowers your building’s carbon footprint and supports your sustainability goals. Additionally, such integration may contribute to meeting BREEAM certification or ESG targets.
Ensuring Water Circulation and Pressure Control
Larger buildings often face challenges in maintaining consistent water pressure and temperature throughout. Incorporating commercial circulators and thermostatic mixing valves can help distribute hot water evenly across all zones.
Reliable pump valves and pressure-regulating equipment also prevent wear and tear on pipes and fixtures.
If your building spans multiple storeys or has complex pipe networks, professional hydraulic balancing ensures pressure remains consistent across all outlets.
Maintaining Your Upgraded System
Once installed, your new system should be placed on a maintenance schedule to preserve efficiency and extend its life. This includes routine flushing, inspection of key components, and performance checks.
Partnering with National Pumps and Boilers for ongoing service ensures your investment remains in top condition and reduces the risk of breakdowns.
Maintenance plan essentials:
- Bi-annual safety checks and performance audits
- Burner and heat exchanger cleaning
- Limescale prevention treatments (especially in hard water areas)
- Review of control systems and temperature settings
Maintenance not only preserves efficiency but ensures your unit remains compliant with health and safety standards.
Compliance and Safety
A new installation must meet UK regulatory standards for gas safety, water temperature controls, and pressure containment. Andrews heaters are designed with built-in safety features, such as anti-legionella cycles and flame failure detection, making compliance straightforward.
Documentation of your system design and testing procedures should also be maintained for audits and inspections.
It’s also a good idea to provide staff with simple operational training, so minor issues can be addressed in-house without delay.
Budgeting for a Successful Upgrade
While upgrading your hot water system is an investment, the long-term cost savings from lower energy bills and reduced maintenance make it worthwhile. Factor in the total cost of ownership, including installation, future servicing, and potential rebates for energy-efficient equipment.
Speak with your facilities or finance team to develop a phased budgeting plan that includes contingencies for equipment room modifications or temporary downtime support.
