In a dutch oven melt butter over medium heat then add bacon and cook until it starts to brown.
Add the onion, celery, garlic, carrots and thyme and saute for about 5 minutes or until veggies begin to soften.
Add potatoes, water, broth and bay leaf.
Bring to a boil and then simmer for about 10 minutes. Potatoes should be almost cooked.
Add the zucchini and corn and simmer for another 10 minutes or until veggies are tender.
Remove the bay leaf then transfer about 2 cups of chowder to a blender and puree until smooth. Add the pureed mixture back to the pot then add creamer and salt and pepper.
