    Now, let’s address the elephant in the room Chicago’s latest political scandal involving campaign funds being spent on hair and makeup. While it may seem frivolous, it’s important to remember that every dollar counts when it comes to politics. And in the case of Mayor Lori Lightfoot’s successor Brandon Johnson, his use of campaign funds for Candidate makeup before the election now being labeled as event expenses has raised eyebrows among some critics. But according to his campaign spokesperson, these payments are justified because they support fair wages for Black and women-owned businesses. While the owner of one such business disputes a $4K charge labeled as event expenses, Johnson’s office has yet to comment on this matter.

    But let’s not dwell on the negativity instead, let’s focus on the positive: the Ideal Logic+ Heat H18 gas boiler!

Frequently Asked Questions:

"How do I replace the diverter valve on my Ideal Logic+ Heat H18 boiler?"

To replace the diverter valve on your Ideal Logic+ Heat H18 boiler, follow these steps:

1. Turn off the power supply to the boiler by switching off the circuit breaker that controls it. Drain the system using a drain valve or pump-down kit to remove any remaining water from the system. Remove the front panel of the boiler by unscrewing the two screws on either side of the display. Set aside the front panel and any associated wiring. Locate the diverter valve, which is located near the bottom left-hand corner of the boiler. It is a small rectangular box with electrical connections attached to it. Disconnect the electrical connectors from the diverter valve by gently pulling them out. Be careful not to damage the connectors or the wiring. Unscrew the two screws holding the old diverter valve in place and carefully remove it from the boiler. Install the new diverter valve in its place, ensuring that the electrical connectors are correctly aligned with the corresponding terminals on the boiler's control board. Secure the new diverter valve in place using the two screws provided. Reconnect the electrical connectors, making sure they fit snugly into their respective sockets. Check that the wiring is not pinched or damaged between the connector and the diverter valve. Reinstall the front panel of the boiler, making sure it is properly aligned with the display and control board. Secure the panel in place using the two screws removed earlier. Turn on the power supply to the boiler by switching back on the circuit breaker. Test the system by running hot water through your taps or radiators to ensure that everything is functioning correctly. Always remember to follow manufacturer's instructions and take all necessary safety precautions when handling electrical components and working on your boiler. If you are unsure about any part of this procedure, it may be best to seek the advice of a qualified plumbing or heating engineer.
